Well I haven't checked it before or after the increment.. but it is working for me.. 

ok, here's the entire function :)
I threw it in getopts because it was relitivly the same thing :)



/* following by Kieran Haughey */
/* returns 0 for FALSE and 1 for TRUE */
/* also returns where the normal text starts from */
char chk_cmdline(int argc,char **argv)
{
    int x,count=0,count2=0;

    argc--;
    argv++;

    for(x=1;x<=argc;x++)
    {
        if((*(*argv) == '-') || (*(*argv) == '/'))
            count++;
        if(strstr(*(argv),"."))
        count2++;
        *(argv++); /* if I replace this with argv++ it doesn't work.. */
                   /* btw, this it the line it gives the warning on */
    }
    if(count == argc && count2==0)
        return 0;
    if(count != argc && count2>0)
        return 1;
    return 0;
}


I should also mention that this function WORKS :).. I use it in Dupey :)..
and Dupey wouldn't accept command line config definition :)..

Now where am I supposed to have been telling porkies?..

Cheers,
Kieran
