23 /* POSIX:2008 defines PATH_MAX to be the maximum number of bytes in a filename,
24 including the terminating NUL byte.
25 <http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/limits.h.html>
26 PATH_MAX is not defined on systems which have no limit on filename length,
29 This file does *not* define PATH_MAX always. Programs that use this file
30 can handle the GNU/Hurd case in several ways:
31 - Either with a package-wide handling, or with a per-file handling,
34 or through a fallback like
36 # define PATH_MAX 8192
38 or through a fallback like
40 # define PATH_MAX pathconf ("/", _PC_PATH_MAX)
48 # ifndef _POSIX_PATH_MAX
49 # define _POSIX_PATH_MAX 256
52 /* Don't include sys/param.h if it already has been. */
53 # if defined HAVE_SYS_PARAM_H && !defined PATH_MAX && !defined MAXPATHLEN
54 # include <sys/param.h>
57 # if !defined PATH_MAX && defined MAXPATHLEN
58 # define PATH_MAX MAXPATHLEN
62 /* On HP-UX, PATH_MAX designates the maximum number of bytes in a filename,
63 *not* including the terminating NUL byte, and is set to 1023.
64 Additionally, when _XOPEN_SOURCE is defined to 500 or more, PATH_MAX is
65 not defined at all any more. */

71 /* The page "Naming Files, Paths, and Namespaces" on msdn.microsoft.com,
72 section "Maximum Path Length Limitation",
73 <http://msdn.microsoft.com/en-us/library/aa365247(v=vs.85).aspx#maxpath>
74 explains that the maximum size of a filename, including the terminating
75 NUL byte, is 260 = 3 + 256 + 1.
76 This is the same value as
77 - FILENAME_MAX in <stdio.h>,
78 - _MAX_PATH in <stdlib.h>,
79 - MAX_PATH in <windef.h>.
80 Undefine the original value, because mingw's <limits.h> gets it wrong. */
