the above code contains many elementary C programming errors. you should
see them if you compile with -Wall. of course, it makes no sense to post
the warnings lest they give some information to the people who might be
able to help you.

i do not see why you need to use arg_temp at all in the first place.
however, given that that's what you chose to do, here is a couple of
points:

> frame_skip = atoi (arg_temp[2]);

did you include <stdlib.h> (that's what you need for atoi) if you did,
gcc should give the following error message:

warning: passing arg 1 of `atoi' makes pointer from integer without a
cast.

arg_temp[1] is _not_ a pointer to a char array.
