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():
	   Since glibc 2.10:
	       _BSD_SOURCE || _POSIX_C_SOURCE >= 200809L || _XOPEN_SOURCE >= 700
	   Before glibc 2.10:
	       _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 appro-
       priately.

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.

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