The top level names are defined with a CTL_ prefix in

-.Ss CTL_DEBUG
-The debugging variables vary from system to system.
-A debugging variable may be added or deleted without need to recompile
-.Fn sysctl
-to know about it.
-Each time it runs,
-.Fn sysctl
-gets the list of debugging variables from the kernel and
-displays their current values.
-The system defines twenty
-.Pq Vt "struct ctldebug"
-variables named
-.Va debug0
-through
-.Va debug19 .
-They are declared as separate variables so that they can be
-individually initialized at the location of their associated variable.
-The loader prevents multiple use of the same variable by issuing errors
-if a variable is initialized in more than one place.
-For example, to export the variable
-.Va dospecialcheck
-as a debugging variable, the following declaration would be used:
-.Pp
-.Bd -literal -offset indent -compact
-int dospecialcheck = 1;
-struct ctldebug debug5 = { "dospecialcheck", &dospecialcheck };

+.Sh SYNOPSIS
+.In wordexp.h
+.Ft int
+.Fn wordexp "const char * restrict words" "wordexp_t * restrict we" "int flags"
+.Ft void
+.Fn wordfree "wordexp_t *we"
+.Sh DESCRIPTION
+The
+.Fn wordexp
+function performs shell-style word expansion on
+.Fa words
+and places the list of words into the
+.Va we_wordv
+member of
+.Fa we ,
+and the number of words into
+.Va we_wordc .
+.Pp
+The
+.Fa flags
+argument is the bitwise inclusive OR of any of the following constants:
+.Bl -tag -width ".Dv WRDE_SHOWERR"
+.It Dv WRDE_APPEND
+Append the words to those generated by a previous call to
+.Fn wordexp .
+.It Dv WRDE_DOOFFS
+As many
+.Dv NULL
+pointers as are specified by the
+.Va we_offs
+member of
+.Fa we
+are added to the front of
+.Va we_wordv .
+.It Dv WRDE_NOCMD
+Disallow command substitution in
+.Fa words .
+See the note in
+.Sx BUGS
+before using this.
+.It Dv WRDE_REUSE
+The
+.Fa we
+argument was passed to a previous successful call to
+.Fn wordexp
+but has not been passed to
+.Fn wordfree .
+The implementation may reuse the space allocated to it.
+.It Dv WRDE_SHOWERR
+Do not redirect shell error messages to
+.Pa /dev/null .
+.It Dv WRDE_UNDEF
+Report error on an attempt to expand an undefined shell variable.
+.El
+.Pp
+The
+.Vt wordexp_t
+structure is defined in
+.In wordexp.h
+as:
+.Bd -literal -offset indent
+typedef struct {
+ size_t we_wordc; /* count of words matched */
+ char **we_wordv; /* pointer to list of words */
+ size_t we_offs; /* slots to reserve in we_wordv */
+} wordexp_t;
+.Ed
+.Pp
+The
+.Fn wordfree
+function frees the memory allocated by
+.Fn wordexp .
+.Sh IMPLEMENTATION NOTES
+The
+.Fn wordexp
+function is implemented as a wrapper around the undocumented
+.Ic wordexp
+shell built-in command.
+.Sh RETURN VALUES
+The
+.Fn wordexp
+function returns zero if successful, otherwise it returns one of the following
+error codes:
+.Bl -tag -width ".Dv WRDE_NOSPACE"
+.It Dv WRDE_BADCHAR
+The
+.Fa words
+argument contains one of the following unquoted characters:
+.Aq newline ,
+.Ql | ,
+.Ql & ,
+.Ql \&; ,
+.Ql < ,
+.Ql > ,
+.Ql \&( ,
+.Ql \&) ,
+.Ql { ,
+.Ql } .
+.It Dv WRDE_BADVAL
+An attempt was made to expand an undefined shell variable and
+.Dv WRDE_UNDEF
+is set in
+.Fa flags .
+.It Dv WRDE_CMDSUB
+An attempt was made to use command substitution and
+.Dv WRDE_NOCMD
+is set in
+.Fa flags .
+.It Dv WRDE_NOSPACE
+Not enough memory to store the result.
+.It Dv WRDE_SYNTAX
+Shell syntax error in
+.Fa words .
+.El
+.Pp
+The
+.Fn wordfree
+function returns no value.
+.Sh ENVIRONMENT
+.Bl -tag -width ".Ev IFS"
+.It Ev IFS
+Field separator.
+.El
+.Sh EXAMPLES
+Invoke the editor on all
+.Pa .c
+files in the current directory
+and
+.Pa /etc/motd
+(error checking omitted):
+.Bd -literal -offset indent
+wordexp_t we;
+
+wordexp("${EDITOR:-vi} *.c /etc/motd", &we, 0);
+execvp(we.we_wordv[0], we.we_wordv);
+.Ed
+.Sh DIAGNOSTICS
+Diagnostic messages from the shell are written to the standard error output
+if
+.Dv WRDE_SHOWERR
+is set in
+.Fa flags .
+.Sh SEE ALSO
+.Xr sh 1 ,
+.Xr fnmatch 3 ,
+.Xr glob 3 ,
+.Xr popen 3 ,
+.Xr system 3
+.Sh STANDARDS
+The
+.Fn wordexp
+and
+.Fn wordfree
+functions conform to
+.St -p1003.1-2001 .
+.Sh BUGS
+Do not pass untrusted user data to
+.Fn wordexp ,
+regardless of whether the
+.Dv WRDE_NOCMD
+flag is set.
+The
+.Fn wordexp
+function attempts to detect input that would cause commands to be
+executed before passing it to the shell
+but it does not use the same parser so it may be fooled.
+.Pp
+The current
+.Fn wordexp
+implementation does not recognize multibyte characters, since the
+shell (which it invokes to perform expansions) does not.

.Sh DESCRIPTION
The
.Fn opendir
function
opens the directory named by
-.Fa dirname ,
+.Fa filename ,
associates a
.Em directory stream
-with it,
-and returns a pointer to be used to identify the
+with it
+and
+returns a pointer to be used to identify the
.Em directory stream
in subsequent operations.
-In the event of an error, NULL
-is returned and
-.Va errno
-will be set to reflect if
-.Fa dirname
-cannot be accessed or if it cannot
+The pointer
+.Dv NULL
+is returned if
+.Fa filename
+cannot be accessed, or if it cannot
.Xr malloc 3
-enough memory to hold the whole thing.
+enough memory to hold the whole thing,
+and sets the global variable
+.Va errno
+to indicate the error.
+.Pp
+The
+.Fn fdopendir
+function is equivalent to the
+.Fn opendir
+function except that the directory is specified by a file descriptor
+.Fa fd
+rather than by a name.
+./"The file offset associated with the file descriptor at the time of the call
+./"determines which entries are returned.
+.Pp
+Upon successful return from
+.Fn fdopendir ,
+the file descriptor is under the control of the system,
+and if any attempt is made to close the file descriptor,
+or to modify the state of the associated description other than by means
+of
+.Fn closedir ,
+.Fn readdir ,
+.Fn readdir_r ,
+or
+.Fn rewinddir ,
+the behavior is undefined.
+Upon calling
+.Fn closedir
+the file descriptor is closed.
+The
+.Dv FD_CLOEXEC
+flag is set on the file descriptor by a successful call to
+.Fn fdopendir .
.Pp
The
.Fn readdir
upon reaching the end of the directory or on error.
In the event of an error,

.Dv DIR
-pointer (e.g.,

+pointer,
+.Fa dirp ,
from which they are derived.
If the directory is closed and then
reopened, prior values returned by
.Fn dirfd
function
returns the integer file descriptor associated with the named
-.Em directory stream

-.Os
-.Sh NAME
-.Nm wordexp
-.Nd "perform shell-style word expansions"
-.Sh SYNOPSIS
-.In wordexp.h
-.Ft int
-.Fo wordexp
-.Fa "const char *restrict words"
-.Fa "wordexp_t *restrict pwordexp"
-.Fa "int flags"
-.Fc
-.Ft void
-.Fo wordfree
-.Fa "wordexp_t *pwordexp"
-.Fc
-.Sh DESCRIPTION
-The
-.Fn wordexp
-function performs shell-style word expansion on
-.Fa words .
-It places the list of words into the
-.Va we_wordv
-member of
-.Fa pwordexp
-and the number of words into
-.Va we_wordc .
-.Pp
-The
-.Fa flags
-argument (see
-.Sx BUGS )
-is the bitwise inclusive OR of any of the following constants:
-.Bl -tag -width ".Dv WRDE_SHOWERR"
-.It Dv WRDE_APPEND
-Append the words to those generated by a previous call to
-.Fn wordexp .
-.It Dv WRDE_DOOFS
-As many
-.Dv NULL
-pointers as are specified by the
-.Va we_offs
-member of
-.Fa pwordexp
-are added to the front of
-.Va we_wordv .
-.It Dv WRDE_NOCMD
-Disallow command substitution in
-.Fa words .
-See the note in
-.Sx BUGS
-before using this.
-.It Dv WRDE_REUSE
-The
-.Fa pwordexp
-argument was passed to a previous successful call to
-.Fn wordexp
-but has not been passed to
-.Fn wordfree .
-The implementation may reuse the space allocated to it.
-.It Dv WRDE_SHOWERR
-Do not redirect shell error messages to
-.Pa /dev/null .
-.It Dv WRDE_UNDEF
-Report error on an attempt to expand an undefined shell variable.
-.El
-.Pp
-The
-.Vt wordexp_t
-structure is defined in
-.In wordexp.h
-as:
-.Bd -literal -offset indent
-typedef struct {
- size_t we_wordc; /* count of words matched */
- char **we_wordv; /* pointer to list of words */
- size_t we_offs; /* slots to reserve in we_wordv */
-} wordexp_t;
-.Ed
-.Pp
-The
-.Fn wordfree
-function frees the memory allocated by
-.Fn wordexp .
-.Sh RETURN VALUES
-The
-.Fn wordexp
-function returns zero if successful, otherwise it returns one of the following
-error codes:
-.Bl -tag -width ".Dv WRDE_NOSPACE"
-.It Dv WRDE_BADCHAR
-The
-.Fa words
-argument contains one of the following unquoted characters:
-.Aq newline ,
-.Ql | ,
-.Ql & ,
-.Ql \&; ,
-.Ql < ,
-.Ql > ,
-.Ql \&( ,
-.Ql \&) ,
-.Ql { ,
-.Ql } .
-.It Dv WRDE_BADVAL
-An attempt was made to expand an undefined shell variable and
-.Dv WRDE_UNDEF
-is set in
-.Fa flags .
-.It Dv WRDE_CMDSUB
-An attempt was made to use command substitution and
-.Dv WRDE_NOCMD
-is set in
-.Fa flags .
-.It Dv WRDE_NOSPACE
-Not enough memory to store the result.
-.It Dv WRDE_SYNTAX
-Shell syntax error in
-.Fa words .
-.El
-.Pp
-The
-.Fn wordfree
-function returns no value.
-.Sh EXAMPLES
-Invoke the editor on all
-.Pa .c
-files in the current directory
-and
-.Pa /etc/motd
-(error checking omitted):
-.Bd -literal -offset indent
-wordexp_t pwordexp;
-
-wordexp("${EDITOR:-vi} *.c /etc/motd", &pwordexp, 0);
-execvp(pwordexp->we_wordv[0], pwordexp->we_wordv);
-.Ed

- This API returns the various standard system directories where apps, resources, etc get installed.
- Because queries can return multiple directories, the API is in the form of an enumeration.
- The directories are returned in search path order; that is, the first place to look is returned first.
- This API may return directories that do not exist yet.
- If NSUserDomain is included in a query, then the results will contain "~" to refer to the user's directory.
- NEXT_ROOT is prepended as necessary to the returned values.
- Some calls might return no directories!
- The buffer that is passed in will be filled with a null-terminated string, possibly containing as many as PATH_MAX-1 characters.
-
- Typical usage:
-
- #include <limits.h>
- #include <NSSystemDirectories.h>
-
- char path[PATH_MAX];
