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 2.19: */ _DEFAULT_SOURCE
	   || /* Glibc 2.19 and earlier: */ _BSD_SOURCE
	   || /* Since glibc 2.10: */ _POSIX_C_SOURCE >= 200809L

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.
