How are the results from glob ordered?

I am reading files in a directory using :

glob_t* globlist;
// initialization.
glob(pattern, GLOB_ERR | GLOB_BRACE, NULL, globlist);

This works well, but now the order of processing for each file is relevant, so I would like to know if there is a specific ordering for the matches, or if there is none, if it is possible to specify in some way.

As quoted from the man page here

The pathnames shall be in sort order as defined by the current setting of the LC_COLLATE category;

By default glob sort the returned names.

From the POSIX reference page:

GLOB_NOSORT

Ordinarily, glob() sorts the matching pathnames according to the current setting of the LC_COLLATE category; see XBD LC_COLLATE. When this flag is used, the order of pathnames returned is unspecified.
