[Playerstage-users] parse_args negative numbers command line arguments

[sudarshan22 <sud...@gm...>]

Hi,

For my project, I need to accept the goal positions (x-pos, y-pos) as
command line arguments. However, if the goal positions are negative numbers,
the program prints an error message and exists. I found out that this is
because of parse_args which does 
while(-1 != (ch = getopt(argc, argv, optflags)))

I am not sure whether it is necessary to call parse_args but I have done so
in my previous programs. If I wanted to include negative numbers as command
line arguments and also call parse_args, what changes do I have to make in
that function so that my program does not exit?

Thanks.
