mkdtemp − create a unique temporary directory
#include <stdlib.h>
char *mkdtemp(char *template);
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
mkdtemp():
Since glibc 2.10:
_BSD_SOURCE || _POSIX_C_SOURCE >= 200809L || _XOPEN_SOURCE >= 700
Before glibc 2.10:
_BSD_SOURCE
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.
The mkdtemp() function returns a pointer to the modified template string on success, and NULL on failure, in which case errno is set appropriately.
|
EINVAL |
The last six characters of template were not XXXXXX. Now template is unchanged. |
Also see mkdir(2) for other possible values for errno.
Available since glibc 2.1.91.
POSIX.1-2008. This function is present on the BSDs.
mkdir(2), mkstemp(3), mktemp(3), tempnam(3), tmpfile(3), tmpnam(3)
