\section{\class{wxFileName}}\label{wxfilename}

wxFileName encapsulates a file name. This class serves two purposes: first, it
provides the functions to split the file names into components and to recombine
these components in the full file name which can then be passed to the OS file
functions (and \helpref{wxWidgets functions}{filefunctions} wrapping them).
Second, it includes the functions for working with the files itself. Note that
to change the file data you should use \helpref{wxFile}{wxfile} class instead.
wxFileName provides functions for working with the file attributes.

\wxheading{Data structures}

Many wxFileName methods accept the path format argument which is by\rtfsp
{\tt wxPATH\_NATIVE} by default meaning to use the path format native for the
current platform.

The path format affects the operation of wxFileName functions in several ways:
first and foremost, it defines the path separator character to use, but it also
affects other things such as whether the path has the drive part or not.

\begin{verbatim}
enum wxPathFormat
{
    wxPATH_NATIVE = 0,      // the path format for the current platform
    wxPATH_UNIX,
    wxPATH_BEOS = wxPATH_UNIX,
    wxPATH_MAC,
    wxPATH_DOS,
    wxPATH_WIN = wxPATH_DOS,
    wxPATH_OS2 = wxPATH_DOS,
    wxPATH_VMS,

    wxPATH_MAX // Not a valid value for specifying path format
}
\end{verbatim}

\latexignore{\rtfignore{\wxheading{Function groups}}}


\membersection{File name format}\label{filenameformat}

wxFileName currently supports the file names in the Unix, DOS/Windows, Mac OS
and VMS formats. Although these formats are quite different, wxFileName tries
to treat them all in the same generic way. It supposes that all file names
consist of the following parts: the volume (also known as drive under Windows
or device under VMS), the path which is a sequence of directory names separated
by the \helpref{path separators}{wxfilenamegetpathseparators} and the full
filename itself which, in turn, is composed from the base file name and the
extension. All of the individual components of the file name may be empty and,
for example, the volume name is always empty under Unix, but if they are all
empty simultaneously, the filename object is considered to be in an invalid
state and \helpref{IsOk}{wxfilenameisok} returns {\tt false} for it.

File names can be case-sensitive or not, the function\rtfsp
\helpref{IsCaseSensitive}{wxfilenameiscasesensitive} allows to determine this.

The rules for determining if the file name is absolute or relative also depends
on the file name format and the only portable way to answer to this question is
to use \helpref{IsAbsolute}{wxfilenameisabsolute} method. To ensure that the
filename is absolute you may use \helpref{MakeAbsolute}{wxfilenamemakeabsolute}.
There is also an inverse function 
\helpref{MakeRelativeTo}{wxfilenamemakerelativeto} which undoes what
\helpref{Normalize(wxPATH\_NORM\_DOTS)}{wxfilenamenormalize} does.

Other functions returning information about the file format provided by this
class are \helpref{GetVolumeSeparator}{wxfilenamegetvolumeseparator},\rtfsp
\helpref{IsPathSeparator}{wxfilenameispathseparator}.

\helpref{IsRelative}{wxfilenameisrelative}


\membersection{File name construction}\label{filenameconstruction}

TODO.


\membersection{File tests}\label{filetests}

Before doing the other tests you should use \helpref{IsOk}{wxfilenameisok} to
verify that the filename is well defined. If it is, 
\helpref{FileExists}{wxfilenamefileexists} can be used to test if a file with
such name exists and \helpref{DirExists}{wxfilenamedirexists} - if a directory
with this name exists.

File names should be compared using \helpref{SameAs}{wxfilenamesameas} method
or \helpref{$==$}{wxfilenameoperatorequal}.


\membersection{File name components}\label{filenamecomponents}

These functions allow to examine and modify the individual directories of the
path:

\helpref{AppendDir}{wxfilenameappenddir}\\
\helpref{InsertDir}{wxfilenameinsertdir}\\
\helpref{GetDirCount}{wxfilenamegetdircount}
\helpref{PrependDir}{wxfilenameprependdir}\\
\helpref{RemoveDir}{wxfilenameremovedir}\\
\helpref{RemoveLastDir}{wxfilenameremovelastdir}

To change the components of the file name individually you can use the
following functions:

\helpref{GetExt}{wxfilenamegetext}\\
\helpref{GetName}{wxfilenamegetname}\\
\helpref{GetVolume}{wxfilenamegetvolume}\\
\helpref{HasExt}{wxfilenamehasext}\\
\helpref{HasName}{wxfilenamehasname}\\
\helpref{HasVolume}{wxfilenamehasvolume}\\
\helpref{SetExt}{wxfilenamesetext}\\
\helpref{ClearExt}{wxfilenameclearext}\\
\helpref{SetEmptyExt}{wxfilenamesetemptyext}\\
\helpref{SetName}{wxfilenamesetname}\\
\helpref{SetVolume}{wxfilenamesetvolume}\\


\membersection{Operations}\label{filenameoperations}

These methods allow to work with the file creation, access and modification
times. Note that not all filesystems under all platforms implement these times
in the same way. For example, the access time under Windows has a resolution of
one day (so it is really the access date and not time). The access time may be
updated when the file is executed or not depending on the platform.

\helpref{GetModificationTime}{wxfilenamegetmodificationtime}\\
\helpref{GetTimes}{wxfilenamegettimes}\\
\helpref{SetTimes}{wxfilenamesettimes}\\
\helpref{Touch}{wxfilenametouch}

Other file system operations functions are:

\helpref{Mkdir}{wxfilenamemkdir}\\
\helpref{Rmdir}{wxfilenamermdir}

\latexignore{\rtfignore{\wxheading{Members}}}


\membersection{wxFileName::wxFileName}\label{wxfilenamewxfilename}

\func{}{wxFileName}{\void}

\func{}{wxFileName}{\param{const wxFileName\& }{filename}}

Copy constructor.

\func{}{wxFileName}{\param{const wxString\& }{fullpath}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Constructor taking a full filename. If it terminates with a '/', a directory path
is constructed (the name will be empty), otherwise a file name and
extension are extracted from it.

\func{}{wxFileName}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Constructor from a directory name and a file name.

Constructor from a directory name, base file name and extension.

\func{}{wxFileName}{\param{const wxString\& }{volume}, \param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Constructor from a volume name, a directory name, base file name and extension.


\membersection{wxFileName::AppendDir}\label{wxfilenameappenddir}

\func{void}{AppendDir}{\param{const wxString\& }{dir}}

Appends a directory component to the path. This component should contain a
single directory name level, i.e. not contain any path or volume separators nor
should it be empty, otherwise the function does nothing (and generates an
assert failure in debug build).


\membersection{wxFileName::Assign}\label{wxfilenameassign}

\func{void}{Assign}{\param{const wxFileName\& }{filepath}}

\func{void}{Assign}{\param{const wxString\& }{fullpath}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

\func{void}{Assign}{\param{const wxString\& }{volume}, \param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{bool }{hasExt}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

\func{void}{Assign}{\param{const wxString\& }{volume}, \param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

\func{void}{Assign}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

\func{void}{Assign}{\param{const wxString\& }{path}, \param{const wxString\& }{name}, \param{const wxString\& }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Creates the file name from various combinations of data.


\membersection{wxFileName::AssignCwd}\label{wxfilenameassigncwd}

\func{static void}{AssignCwd}{\param{const wxString\& }{volume = wxEmptyString}}

Makes this object refer to the current working directory on the specified
volume (or current volume if {\it volume} is empty).

\wxheading{See also}

\helpref{GetCwd}{wxfilenamegetcwd}


\membersection{wxFileName::AssignDir}\label{wxfilenameassigndir}

\func{void}{AssignDir}{\param{const wxString\& }{dir}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Sets this file name object to the given directory name. The name and extension
will be empty.


\membersection{wxFileName::AssignHomeDir}\label{wxfilenameassignhomedir}

\func{void}{AssignHomeDir}{\void}

Sets this file name object to the home directory.


\membersection{wxFileName::AssignTempFileName}\label{wxfilenameassigntempfilename}

\func{void}{AssignTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}

The function calls \helpref{CreateTempFileName}{wxfilenamecreatetempfilename} to
create a temporary file and sets this object to the name of the file. If a
temporary file couldn't be created, the object is put into the\rtfsp
\helpref{invalid}{wxfilenameisok} state.


\membersection{wxFileName::Clear}\label{wxfilenameclear}

\func{void}{Clear}{\void}

Reset all components to default, uninitialized state.


\membersection{wxFileName::ClearExt}\label{wxfilenameclearext}

\func{void}{SetClearExt}{\void}

Removes the extension from the file name resulting in a 
file name with no trailing dot.

\wxheading{See also}

\helpref{SetExt}{wxfilenamesetext}
\helpref{SetEmptyExt}{wxfilenamesetemptyext}

\membersection{wxFileName::CreateTempFileName}\label{wxfilenamecreatetempfilename}

\func{static wxString}{CreateTempFileName}{\param{const wxString\& }{prefix}, \param{wxFile *}{fileTemp = {\tt NULL}}}

Returns a temporary file name starting with the given {\it prefix}. If
the {\it prefix} is an absolute path, the temporary file is created in this
directory, otherwise it is created in the default system directory for the
temporary files or in the current directory.

If the function succeeds, the temporary file is actually created. If\rtfsp
{\it fileTemp} is not {\tt NULL}, this file will be opened using the name of
the temporary file. When possible, this is done in an atomic way ensuring that
no race condition occurs between the temporary file name generation and opening
it which could often lead to security compromise on the multiuser systems.
If {\it fileTemp} is {\tt NULL}, the file is only created, but not opened.

Under Unix, the temporary file will have read and write permissions for the
owner only to minimize the security problems.

\wxheading{Parameters}

\docparam{prefix}{Prefix to use for the temporary file name construction}

\docparam{fileTemp}{The file to open or {\tt NULL} to just get the name}

\wxheading{Return value}

The full temporary file name or an empty string on error.

The {\it dir} parameter may have trailing path separator or not.



\membersection{wxFileName::FileExists}\label{wxfilenamefileexists}

\constfunc{bool}{FileExists}{\void}

\func{static bool}{FileExists}{\param{const wxString\& }{file}}

\membersection{wxFileName::GetCwd}\label{wxfilenamegetcwd}

\func{static wxString}{GetCwd}{\param{const wxString\& }{volume = ""}}

Retrieves the value of the current working directory on the specified volume. If

\constfunc{wxString}{GetPath}{\param{int }{flags = {\tt wxPATH\_GET\_VOLUME}}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Returns the path part of the filename (without the name or extension). The
possible flags values are:

\twocolwidtha{5cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf wxPATH\_GET\_VOLUME}}{Return the path with the volume (does
nothing for the filename formats without volumes), otherwise the path without
volume part is returned.}
\twocolitem{{\bf wxPATH\_GET\_SEPARATOR}}{Return the path with the trailing
separator, if this flag is not given there will be no separator at the end of
the path.}
\end{twocollist}


\membersection{wxFileName::GetPathSeparator}\label{wxfilenamegetpathseparator}

\func{static wxChar}{GetPathSeparator}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

Returns the usually used path separator for this format. For all formats but 
{\tt wxPATH\_DOS} there is only one path separator anyhow, but for DOS there
are two of them and the native one, i.e. the backslash is returned by this
method.

\wxheading{See also}

\helpref{GetPathSeparators}{wxfilenamegetpathseparators}


\membersection{wxFileName::GetPathSeparators}\label{wxfilenamegetpathseparators}

\func{static wxString}{GetPathSeparators}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

Returns the string containing all the path separators for this format. For all
formats but {\tt wxPATH\_DOS} this string contains only one character but for
DOS and Windows both {\tt '/'} and {\tt '\textbackslash'} may be used as
separators.

\wxheading{See also}

\helpref{GetPathSeparator}{wxfilenamegetpathseparator}


\membersection{wxFileName::GetPathTerminators}\label{wxfilenamegetpathterminators}

\constfunc{wxString}{GetShortPath}{\void}

Return the short form of the path (returns identity on non-Windows platforms).


\membersection{wxFileName::GetTimes}\label{wxfilenamegettimes}

\constfunc{bool}{GetTimes}{\param{wxDateTime* }{dtAccess}, \param{wxDateTime* }{dtMod}, \param{wxDateTime* }{dtCreate}}

Returns the last access, last modification and creation times. The last access
time is updated whenever the file is read or written (or executed in the case
of Windows), last modification time is only changed when the file is written
to. Finally, the creation time is indeed the time when the file was created
under Windows and the inode change time under Unix (as it is impossible to
retrieve the real file creation time there anyhow) which can also be changed
by many operations after the file creation.

Any of the pointers may be {\tt NULL} if the corresponding time is not
needed.

\wxheading{Return value}

{\tt true} on success, {\tt false} if we failed to retrieve the times.


\membersection{wxFileName::GetVolume}\label{wxfilenamegetvolume}

\constfunc{wxString}{GetVolume}{\void}

doesn't have one or if the file system doesn't support volumes at all (for
example, Unix).


\membersection{wxFileName::GetVolumeSeparator}\label{wxfilenamegetvolumeseparator}

\func{static wxString}{GetVolumeSeparator}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

Inserts a directory component before the zero-based position in the directory
list. Please see \helpref{AppendDir}{wxfilenameappenddir} for important notes.


\membersection{wxFileName::IsAbsolute}\label{wxfilenameisabsolute}

\func{bool}{IsAbsolute}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

Returns {\tt true} if this filename is absolute.


\membersection{wxFileName::IsCaseSensitive}\label{wxfilenameiscasesensitive}

\func{static bool}{IsCaseSensitive}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

Returns {\tt true} if the file names of this type are case-sensitive.


\membersection{wxFileName::IsOk}\label{wxfilenameisok}

\constfunc{bool}{IsOk}{\void}

Returns {\tt true} if the filename is valid, {\tt false} if it is not
initialized yet. The assignment functions and
\helpref{Clear}{wxfilenameclear} may reset the object to the uninitialized,
invalid state (the former only do it on failure).


\membersection{wxFileName::IsPathSeparator}\label{wxfilenameispathseparator}

\func{static bool}{IsPathSeparator}{\param{wxChar }{ch}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Returns {\tt true} if the char is a path separator for this format.


\membersection{wxFileName::IsRelative}\label{wxfilenameisrelative}

\func{bool}{IsRelative}{\param{wxPathFormat }{format = wxPATH\_NATIVE}}

Returns {\tt true} if this filename is not absolute.


\membersection{wxFileName::IsDir}\label{wxfilenameisdir}

\constfunc{bool}{IsDir}{\void}

Returns {\tt true} if this object represents a directory, {\tt false} otherwise
(i.e. if it is a file). Note that this method doesn't test whether the
directory or file really exists, you should use 
\helpref{DirExists}{wxfilenamedirexists} or 
\helpref{FileExists}{wxfilenamefileexists} for this.

\membersection{wxFileName::MacFindDefaultTypeAndCreator}\label{wxfilenamemacfinddefaulttypeandcreator}

\func{static bool}{MacFindDefaultTypeAndCreator}{\param{const wxString\& }{ext}, \param{wxUint32* }{type}, \param{wxUint32* }{creator}}

\func{static void}{MacRegisterDefaultTypeAndCreator}{\param{const wxString\& }{ext}, \param{wxUint32 }{type}, \param{wxUint32 }{creator}}

On Mac OS, registers application defined extensions and their default type and creator.

\membersection{wxFileName::MacSetDefaultTypeAndCreator}\label{wxfilenamemacsetdefaulttypeandcreator}

\func{bool}{MacSetDefaultTypeAndCreator}{\void}

On Mac OS, looks up the appropriate type and creator from the registration and then sets it.

\membersection{wxFileName::MakeAbsolute}\label{wxfilenamemakeabsolute}

\func{bool}{MakeAbsolute}{\param{const wxString\& }{cwd = wxEmptyString}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Make the file name absolute. This is a shortcut for
{\tt \helpref{Normalize}{wxfilenamenormalize}(wxPATH\_NORM\_DOTS | wxPATH\_NORM\_ABSOLUTE | wxPATH\_NORM\_TILDE, cwd, format)}.

\wxheading{See also}

\helpref{MakeRelativeTo}{wxfilenamemakerelativeto},

\membersection{wxFileName::MakeRelativeTo}\label{wxfilenamemakerelativeto}

\func{bool}{MakeRelativeTo}{\param{const wxString\& }{pathBase = wxEmptyString}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

This function tries to put this file name in a form relative to {\it pathBase}.
In other words, it returns the file name which should be used to access this
file if the current directory were {\it pathBase}.

\docparam{pathBase}{the directory to use as root, current directory is used by
default}

\docparam{format}{the file name format, native by default}

\wxheading{Return value}

{\tt true} if the file name has been changed, {\tt false} if we failed to do
anything with it (currently this only happens if the file name is on a volume
different from the volume specified by {\it pathBase}).

\wxheading{See also}

try to create each directory in the path and also don't return an error
if the target directory already exists.}

\wxheading{Return value}

Returns {\tt true} if the directory was successfully created, {\tt false}
otherwise.


\membersection{wxFileName::Normalize}\label{wxfilenamenormalize}

\func{bool}{Normalize}{\param{int }{flags = wxPATH\_NORM\_ALL}, \param{const wxString\& }{cwd = wxEmptyString}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Normalize the path. With the default flags value, the path will be
made absolute, without any ".." and "." and all environment
variables will be expanded in it.

\docparam{flags}{The kind of normalization to do with the file name. It can be
any or-combination of the following constants:

\begin{twocollist}
\twocolitem{{\bf wxPATH\_NORM\_ENV\_VARS}}{replace env vars with their values}

Changes the current working directory.


\membersection{wxFileName::SetExt}\label{wxfilenamesetext}

\func{void}{SetExt}{\param{const wxString\& }{ext}}

Sets the extension of the file name. Setting an empty string
as the extension will remove the extension resulting in a file 
name without a trailing dot, unlike a call to 
\helpref{SetEmptyExt}{wxfilenamesetemptyext}.

\wxheading{See also}

\helpref{SetEmptyExt}{wxfilenamesetemptyext}

\func{static void}{SplitPath}{\param{const wxString\& }{fullpath}, \param{wxString* }{volume}, \param{wxString* }{path}, \param{wxString* }{name}, \param{wxString* }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

\func{static void}{SplitPath}{\param{const wxString\& }{fullpath}, \param{wxString* }{path}, \param{wxString* }{name}, \param{wxString* }{ext}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

This function splits a full file name into components: the volume (with the
first version) path (including the volume in the second version), the base name
and the extension. Any of the output parameters ({\it volume}, {\it path}, 
{\it name} or {\it ext}) may be {\tt NULL} if you are not interested in the
value of a particular component. Also, {\it fullpath} may be empty on entry.

On return, {\it path} contains the file path (without the trailing separator), 
{\it name} contains the file name and {\it ext} contains the file extension
without leading dot. All three of them may be empty if the corresponding
component is. The old contents of the strings pointed to by these parameters
will be overwritten in any case (if the pointers are not {\tt NULL}).

Note that for a filename ``foo.'' the extension is present, as indicated by the
trailing dot, but empty. If you need to cope with such cases, you should use 
\arg{hasExt} instead of relying on testing whether \arg{ext} is empty or not.


\membersection{wxFileName::SplitVolume}\label{wxfilenamesplitvolume}

\func{static void}{SplitVolume}{\param{const wxString\& }{fullpath}, \param{wxString* }{volume}, \param{wxString* }{path}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}

Splits the given \arg{fullpath} into the volume part (which may be empty) and
the pure path part, not containing any volume.

\membersection{wxFileName::Touch}\label{wxfilenametouch}

\func{bool}{Touch}{\void}

Sets the access and modification times to the current moment.


\membersection{wxFileName::operator=}\label{wxfilenameoperatorassign}

\func{wxFileName\& operator}{operator=}{\param{const wxFileName\& }{filename}}

\func{wxFileName\& operator}{operator=}{\param{const wxString\& }{filename}}

Assigns the new value to this filename object.


\membersection{wxFileName::operator==}\label{wxfilenameoperatorequal}

\constfunc{bool operator}{operator==}{\param{const wxFileName\& }{filename}}

\constfunc{bool operator}{operator==}{\param{const wxString\& }{filename}}

Returns {\tt true} if the filenames are equal. The string {\it filenames} is
interpreted as a path in the native filename format.


\membersection{wxFileName::operator!=}\label{wxfilenameoperatornotequal}

\constfunc{bool operator}{operator!=}{\param{const wxFileName\& }{filename}}

\constfunc{bool operator}{operator!=}{\param{const wxString\& }{filename}}

Returns {\tt true} if the filenames are different. The string {\it filenames}
is interpreted as a path in the native filename format.
