pathfind(3G) DG/UX 5.4.2 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. ./ is not
prepended at the occurrence of the first match; 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).

area that is reused on subsequent calls to pathfind.
