Creates a directory and any parent directories that may not exist similar to
'mkdir -p'. If the file system does not support creating directories, this
function will fail, setting error to G_IO_ERROR_NOT_SUPPORTED.
For a local GFile the newly created directories will have the default
(current) ownership and permissions of the current process.
If cancellable is not NULL, then the operation can be cancelled by
triggering the cancellable object from another thread. If the operation
was cancelled, the error G_IO_ERROR_CANCELLED will be returned.
Since 2.18
