       pathfind - search for named file in named directories

       cc [ flag ... ] file ... -lgen [ library ... ]
       #include <libgen.h>

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

       The  pathfind() function searches the directories named in path for the
       file name. The directories named in path are separated by  colons  (:).
       The  mode  argument  is	a string of option letters chosen from the set

       │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 non-zero	   │

       Options read, write, and execute are checked relative to the real  (not
       the effective) user ID and group ID of the current process.

       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. A  slash  (/)
       character  is  not  prepended  at  the  occurrence  of the first match;
       rather, the unadorned name is returned.

       Example 1 Example of finding the ls command using the PATH  environment

       To find the ls command using the PATH environment variable:

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

       The  pathfind()	function  returns  a (char *) value containing static,
       thread-specific data that will be overwritten upon the next  call  from
       the same thread.

       If the file name with all 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 no match is found, pathname() returns a null pointer, ((char *) 0).

       See attributes(5) for descriptions of the following attributes:

       │MT-Level       │ MT-Safe	 │

       sh(1), test(1), access(2), mknod(2), stat(2), getenv(3C), attributes(5)

       The string pointed to by the returned pointer is stored in an area that
       is  reused  on subsequent calls to pathfind(). The string should not be
       deallocated by the caller.

       When compiling multithreaded applications, the _REENTRANT flag must  be
       defined	on  the compile line.  This flag should only be used in multi‐
