** MAXPATHLEN and PATH_MAX
|
|
|
|
**
|
|
|
|
** On most systems MAXPATHLEN is defined in sys/param.h to be 1024. Of
|
|
|
|
** those that this is not true, again most define PATH_MAX in limits.h
|
|
|
|
** or sys/limits.h which usually gets included by limits.h. On the few
|
|
|
|
** remaining systems that neither statement is true, _POSIX_PATH_MAX
|
|
|
|
** is defined.
|
|
|
|
**
|
|
|
|
** So:
|
|
|
|
** 1. If PATH_MAX is defined just use it.
|
|
|
|
** 2. If MAXPATHLEN is defined but not PATH_MAX, then define
|
|
|
|
** PATH_MAX in terms of MAXPATHLEN.
|
|
|
|
** 3. If neither is defined, include limits.h and check for
|
|
|
|
** PATH_MAX again.
|
|
|
|
** 3.1 If we now have PATHSIZE, define PATH_MAX in terms of that.
|
|
|
|
** and ignore the rest. Since _POSIX_PATH_MAX (checked for
|
|
|
|
** next) is the *most* restrictive (smallest) value, if we
|
|
|
|
** trust _POSIX_PATH_MAX, several of our buffers are too small.
|
|
|
|
** 4. If PATH_MAX is still not defined but _POSIX_PATH_MAX is,
|
|
|
|
** then define PATH_MAX in terms of _POSIX_PATH_MAX.
|
|
|
|
** 5. And if even _POSIX_PATH_MAX doesn't exist just put in
|
|
|
|
** a reasonable value.
|
|
|
|
** *. All in all, this is an excellent argument for using pathconf()
|
|
|
|
** when at all possible. Or better yet, dynamically allocate
|
|
|
|
** our buffers and use getcwd() not getwd().
|
|
|
|
**
|
|
|
|
** This works on:
|
|
|
|
** Sun Sparc 10 SunOS 4.1.3 & Solaris 1.2
|
|
|
|
** HP 9000/700 HP/UX 8.07 & HP/UX 9.01
