NAME
mkdirp(), rmdirp() — create, remove directories in a path
SYNOPSIS
#include <libgen.h>
int mkdirp
(const char *path,
mode_t mode);
int rmdirp
(char *d,
char *d1);
DESCRIPTION
mkdirp
creates all the missing directories in the given
path
with the given
mode
(see
chmod(2)
for the values of
mode.)
The protection part of the
mode
argument is modified by the
process's file creation mask
(see
umask(2)).
rmdirp
removes directories in path
d.
This removal starts at the end of the path
and moves back toward the root as far as possible.
If an error occurs, the remaining path is stored in
d1.
rmdirp
returns a 0 only if it is
able to remove every directory in the path.
To use these interfaces, link in the libgen library by specifying
-lgen.
For example:
RETURN VALUE
If a needed directory cannot be created,
mkdirp
returns -1 and sets
errno
to one of the
mkdir
error numbers.
If all the directories are
created, or existed to begin with, it returns zero.
EXAMPLES
/* create scratch directories */
if(mkdirp("/tmp/sub1/sub2/sub3", 0755) == -1) {
fprintf(stderr, "cannot create directory");
exit(1);
}
chdir("/tmp/sub1/sub2/sub3");
.
.
.
/* cleanup */
chdir( /tmp");"
rmdirp("sub1/sub2/sub3");
WARNINGS
mkdirp
uses
malloc
to allocate
temporary space for the string.
rmdirp
returns
-2
if a "." or ".." is in the path. It returns
-3
if an
attempt is made to remove the current directory.
If an error occurs other than one
of these two errors,
rmdirp
returns
-1.
