Yes.  That does the trick.  After sending off my this reply to which you
are referring, I did just that - well, I actually created a function
that simply had the line "return strcmp(...);".  After reading this
message, I tried it by directly calling strcmp() and it worked
perfectly. (Another aspect I overlooked).

It's quite simple, once you see it.  If I'd given it more thought, I
should have seen that there was a good reason for having the
g_string_find_custom() function, but I was concentrating too hard on
trying to match by the contents of g_string.  Actually, this is as
powerful as having a special g_string_find_str(), which I suggested in
my previous message.

Thanks to both of you for your help (on something I should have seen
already).
