Feature Test Macro Requirements for glibc (see
feature_test_macros(7)):
mkdtemp():

|| /* Since glibc 2.10: */ _POSIX_C_SOURCE >= 200809L
Описание (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.
Возвращаемое значение (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 to indicate the error.
Ошибки (Error)
EINVAL The last six characters of template were not XXXXXX. Now
template is unchanged.
Also see mkdir(2) for other possible values for errno.
Версии (Versions)
Available since glibc 2.1.91.
