MKDTEMP(3) Linux Programmer's Manual MKDTEMP(3)
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.
ATTRIBUTES
Multithreading (see pthreads(7))
The mkdtemp() function is thread-safe.
CONFORMING TO
POSIX.1-2008. This function is present on the BSDs.
