pathfind(3G)                     UNIX System V                     pathfind(3G)


NAME
      pathfind - search for named file in named directories

SYNOPSIS
      cc [flag ...] file ...  -lgen [library ...]

      #include <libgen.h>

      char *pathfind (const char *path, const char *name, const char
          *mode);

DESCRIPTION
      pathfind searches the directories named in path for the file name.  The
      directories named in path are separated by semicolons.  mode is a string
      of option letters chosen from the set rwxfbcdpugks:
                             Letter   Meaning
                             __________________________
                               r      readable
                               w      writable
                               x      executable
                               f      normal file
                               b      block special
                               c      character special
                               d      directory
                               p      FIFO (pipe)
                               u      set user ID bit
                               g      set group ID bit
                               k      sticky bit
                               s      size nonzero
      Options read, write, and execute are checked relative to the real (not
      the effective) user ID and group ID of the current process.

      If the file name, with all the characteristics specified by mode, is
      found in any of the directories specified by path, then pathfind returns
      a pointer to a string containing the member of path, followed by a slash
      character (/), followed by name.

      If name begins with a slash, it is treated as an absolute path name, and
      path is ignored.

      An empty path member is treated as the current directory.  rather, the
      unadorned name is returned.

EXAMPLES
      To find the ls command using the PATH environment variable:

            pathfind (getenv ("PATH"), "ls", "rx")

DIAGNOSTICS
      If no match is found, pathname returns a null pointer, ((char *) 0).

NOTES
      The string pointed to by the returned pointer is stored in a static area
      that is reused on subsequent calls to pathfind.
