I am having problems using command line arguments in my programs. I am used
to string handling in Turbo c++, so there is some differences in that
aspect. But tell me what you see that is wrong with the code below. It is
supposed to set the frame_skip variable according to the option -f2 if
present.
c:\game\source\freedom -f2
int main(int argc, char *argv[ ]);
/* some miscellaneous code here */
char arg_temp[10];
strcpy (arg_temp, argv[1]);
if ((arg_temp[0] == '-') && (arg_temp[1] == 'f'))
frame_skip = atoi (arg_temp[2]);

The above code works in Turbo c, but chokes in DJGPP, with numerous
warnings and errors. Also to debug it i would use a printf statement like
the below.
printf ("%s",arg_temp[1]);
but even though i declared it to be a string with only ten elements, it
would display a very long a wierd looking string instead of just a single
letter. And yes i did type in the parameter on the command line when i ran
it. any help would be greatly appreciated. Thanks in advance.
