NAME
       mkdtemp - create a unique temporary directory

SYNOPSIS
       #include <stdlib.h>

       char *mkdtemp(char *template);

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.

CONFORMING TO
       Introduced in OpenBSD 2.2.  Available since glibc 2.1.91.
