Template for directory name, as in glib.global.mkdtemp, basename only, or null for a default template
The actual name used. This string should be freed with glib.global.gfree when not needed any longer and is is in the GLib file name encoding. In case of errors, null is returned and error will be set.
Creates a subdirectory in the preferred directory for temporary files (as returned by glib.global.getTmpDir).
tmpl should be a string in the GLib file name encoding containing a sequence of six 'X' characters, as the parameter to glib.global.mkstemp. However, unlike these functions, the template should only be a basename, no directory components are allowed. If template is null, a default template is used.
Note that in contrast to glib.global.mkdtemp (and mkdtemp()) tmpl is not modified, and might thus be a read-only literal string.
