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 de- clared 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 ap- propriately. ERRORS EINVAL The last six characters of template were not XXXXXX. Now tem- plate is unchanged. Also see <A HREF="/man2/mkdir">mkdir(2)</A> for other possible values for errno. VERSIONS Available since glibc 2.1.91.
