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

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.

CONFORMING TO

POSIX.1-2008. This function is present on the BSDs.
