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.
The mkdtemp() function returns a pointer to the modified template string
on success, and NULL on failure, in which case errno is set to indicate
- The last six characters of template were not XXXXXX. Now
template is unchanged.
Also see mkdir(2) for other possible values for
Available since glibc 2.1.91.
