-.Dt REALPATH 3
-.Os
-.Sh NAME
-.Nm realpath
-.Nd returns the canonicalized absolute pathname
-.\" .Sh LIBRARY
-.\" .Lb libc
-.Sh SYNOPSIS
-.In stdlib.h
-.Ft "char *"
-.Fo realpath
-.Fa "const char *restrict file_name"
-.Fa "char *restrict resolved_name"
-.Fc
-.Sh DESCRIPTION
-The
-.Fn realpath
-function resolves all symbolic links, extra
-.Dq /
-characters, and references to
-.Pa /./
-and
-.Pa /../
-in
-.Fa file_name .
-If the
-.Fa resolved_name
-argument
-is non-NULL, the resulting absolute pathname is copied there (it
-.Em must
-refer to a buffer capable of storing at least
-.Dv PATH_MAX
-characters).
-.Pp
-As a permitted extension to the standard, if
-.Fa resolved_name
-is NULL, 
-memory is allocated for the resulting absolute pathname, and is returned by
-.Fn realpath .
-This memory should be freed by a call to
-.Xr free 3
-when no longer needed.
-.Pp
-The
-.Fn realpath
-function will resolve both absolute and relative paths
-and return the absolute pathname corresponding to
-.Fa file_name .
-All components of
-.Fa file_name
-must exist when
-.Fn realpath
-is called.
-.Sh "RETURN VALUES"
-On success, the
-.Fn realpath
-function returns the address of the resulting absolute pathname, which is
-.Fa resolved_name
-if it was non-NULL, or the address of newly allocated memory.
-If an error occurs,
-.Fn realpath
-returns
-.Dv NULL .
-If
-.Fa resolved_name
-was non-NULL, it will
-contains the pathname which caused the problem.
-.Sh ERRORS
-The function
-.Fn realpath
-may fail and set the external variable
-.Va errno
-for any of the errors specified for the library functions
-.Xr alloca 3 ,
-.Xr getattrlist 2 ,
-.Xr getcwd 3 ,
-.Xr lstat 2 ,
-.Xr readlink 2 ,
-.Xr stat 2 ,
-and
-.Xr strdup 3 .
-.\" .Sh CAVEATS
-.\" This implementation of
-.\" .Fn realpath
-.\" differs slightly from the Solaris implementation.
-.\" The
-.\" .Bx 4.4
-.\" version always returns absolute pathnames,
-.\" whereas the Solaris implementation will,
-.\" under certain circumstances, return a relative
-.\" .Fa resolved_name
-.\" when given a relative
-.\" .Fa file_name .
-.Sh LEGACY SYNOPSIS
-.Fd #include <sys/param.h>
-.Fd #include <stdlib.h>
-.Pp
-The include file
-.In sys/param.h
-is necessary.
-.Sh LEGACY DESCRIPTION
-In legacy mode,
-the last component of
-.Fa file_name
-does not need to exist when
-.Fn realpath
-is called.
-.Sh "SEE ALSO"
-.Xr free 3 ,
-.Xr getcwd 3 ,
-.Xr compat 5
-.Sh HISTORY
-The
-.Fn realpath
-function first appeared in
-.Bx 4.4 .
