if (strcmp(sCommandArg, "") == 0), which it never does... by RaceProUK on 11-21-2003 at 09:46 PM

Can someone please help me figure out why

code:
if (strcmp(sCommandArg, "") == 0)
never evaluates to 'TRUE'?
*-)
Or do I just not know how to use pointers properly?

Probably because Patchou rejects commands with no param if it's supposed to have one.

I seem to have forgotten to mention sCommandArg is a pointer.

How?

I have tested this, and I found that when no argument is supplied, *sCommandArg is the NULL character.

if (strlen(sCommandArg) == 0), which it does with no arguments. I should have used that to start off with really.
