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(3,n) 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(3,n) constant, but should be
declared as a character array.
RETURN VALUE
The mkdtemp() function returns a pointer to the modified template
string(3,n) on success, and NULL on failure, in(1,8) which case errno is set(7,n,1 builtins)
appropriately.
ERRORS
EINVAL The last six characters of template were not XXXXXX. Now tem-
plate is unchanged.
Also see mkdir(1,2)(2) for other possible values for errno.
CONFORMING TO
Introduced in(1,8) OpenBSD 2.2. Available since glibc 2.1.91.
