- Good day,
-
- I'm using gcc on a sun4(4/75).
- I'd like to know how to determine the number of bytes passed to a
- function. I've got a varargs function and would like to determine from
- within the function how many arguments were passed. Also I'd be interested
- in any information on the call convention of gcc, i.e. what a argument stack
- looks like, what does gcc do with passed structures, what is the size limit
- of data passed on the stack.
-
- Thanks.
