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