\section{\class{wxPlatformInfo}}\label{wxplatforminfo}

This class holds informations about the operating system and the toolkit that the application
is running under and some basic architecture info of the machine where it's running.

\wxheading{Data structures}

The following are the operating systems which are recognized by wxWidgets
and whose version can be detected at run-time. The values of the constants
are chosen so that they can be combined as flags; this allows to check
for operating system {\it families} like e.g. wxOS\_MAC and wxOS\_UNIX.

\begin{verbatim}
enum wxOperatingSystemId
{
    wxOS_UNKNOWN = 0,                 // returned on error

    wxOS_MAC_OS         = 1 << 0,     // Apple Mac OS 8/9/X with Mac paths
    wxOS_MAC_OSX_DARWIN = 1 << 1,     // Apple Mac OS X with Unix paths
    wxOS_MAC = wxOS_MAC_OS|wxOS_MAC_OSX_DARWIN,

    wxOS_WINDOWS_9X     = 1 << 2,     // Windows 9x family (95/98/ME)
    wxOS_WINDOWS_NT     = 1 << 3,     // Windows NT family (NT/2000/XP)
    wxOS_WINDOWS_MICRO  = 1 << 4,     // MicroWindows
    wxOS_WINDOWS_CE     = 1 << 5,     // Windows CE (Window Mobile)
    wxOS_WINDOWS = wxOS_WINDOWS_9X      |
                   wxOS_WINDOWS_NT      |
                   wxOS_WINDOWS_MICRO   |
                   wxOS_WINDOWS_CE,

    wxOS_UNIX_LINUX     = 1 << 6,       // Linux
    wxOS_UNIX_FREEBSD   = 1 << 7,       // FreeBSD
    wxOS_UNIX_OPENBSD   = 1 << 8,       // OpenBSD
    wxOS_UNIX_NETBSD    = 1 << 9,       // NetBSD
    wxOS_UNIX_SOLARIS   = 1 << 10,      // SunOS
    wxOS_UNIX_AIX       = 1 << 11,      // AIX
    wxOS_UNIX_HPUX      = 1 << 12,      // HP/UX
    wxOS_UNIX = wxOS_UNIX_LINUX     |
                wxOS_UNIX_FREEBSD   |
                wxOS_UNIX_OPENBSD   |
                wxOS_UNIX_NETBSD    |
                wxOS_UNIX_SOLARIS   |
                wxOS_UNIX_AIX       |
                wxOS_UNIX_HPUX,

    wxOS_DOS            = 1 << 15,      // Microsoft DOS
    wxOS_OS2            = 1 << 16       // OS/2
};
\end{verbatim}

The list of wxWidgets ports. Some of them can be used with more than
a single (native) toolkit; e.g. wxWinCE port sources can be used with
smartphones, pocket PCs and handheld devices SDKs.

\begin{verbatim}
enum wxPortId
{
    wxPORT_UNKNOWN  = 0,            // returned on error

    wxPORT_BASE     = 1 << 0,       // wxBase, no native toolkit used

    wxPORT_MSW      = 1 << 1,       // wxMSW, native toolkit is Windows API
    wxPORT_MOTIF    = 1 << 2,       // wxMotif, using [Open]Motif or Lesstif
    wxPORT_GTK      = 1 << 3,       // wxGTK, using GTK+ 1.x, 2.x, GPE or Maemo
    wxPORT_MGL      = 1 << 4,       // wxMGL, using wxUniversal
    wxPORT_X11      = 1 << 5,       // wxX11, using wxUniversal
    wxPORT_OS2      = 1 << 6,       // wxOS2, using OS/2 Presentation Manager
    wxPORT_MAC      = 1 << 7,       // wxMac, using Carbon or Classic Mac API
    wxPORT_COCOA    = 1 << 8,       // wxCocoa, using Cocoa NextStep/Mac API
    wxPORT_WINCE    = 1 << 9,       // wxWinCE, toolkit is WinCE SDK API
    wxPORT_PALMOS   = 1 << 10       // wxPalmOS, toolkit is PalmOS API
};
\end{verbatim}

The architecture of the operating system (regardless of the build environment
of wxWidgets library - see \helpref{wxIsPlatform64bit}{wxisplatform64bit} documentation
for more info).

\begin{verbatim}
enum wxArchitecture
{
    wxARCH_INVALID = -1,        // returned on error

    wxARCH_32,                  // 32 bit
    wxARCH_64,

    wxARCH_MAX
}
\end{verbatim}

The endian-ness of the machine.

\begin{verbatim}
enum wxEndianness
{
    wxENDIAN_INVALID = -1,      // returned on error

    wxENDIAN_BIG,               // 4321
    wxENDIAN_LITTLE,            // 1234
    wxENDIAN_PDP,               // 3412

    wxENDIAN_MAX
}
\end{verbatim}
