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 tem-
plate is unchanged.
Also see mkdir(2) for other possible values for errno.
VERSIONS
Available since glibc 2.1.91.
ATTRIBUTES
Multithreading (see pthreads(7))
The mkdtemp() function is thread-safe.
CONFORMING TO
POSIX.1-2008. This function is present on the BSDs.
