NAME
mkdtemp - create a unique temporary directory
SYNOPSIS
#include <stdlib.h>
char *mkdtemp(char *template);
Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
mkdtemp():
_BSD_SOURCE
DESCRIPTION
The
mkdtemp()
function generates a uniquely named temporary
directory from template.
The last six characters of template
must be XXXXXX and these are replaced with a string that makes the
directory name unique.
The directory is then created with
permissions 0700.
Since it will be modified,
template
must not be a string constant, but should be declared as a character array.
RETURN VALUE
The
mkdtemp()
function returns a pointer to the modified template
string on success, and NULL on failure, in which case
errno
is set appropriately.
ERRORS
- EINVAL
-
The last six characters of template were not XXXXXX.
Now template is unchanged.
Also see
mkdir(2)
for other possible values for errno.
VERSIONS
Available since glibc 2.1.91.

POSIX.1-2008.
