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
|| /* Since glibc 2.10: */
-
(_POSIX_C_SOURCE >= 200809L || _XOPEN_SOURCE >= 700)
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.

mkdtemp()
function is thread-safe.
