I'm doing some lovely socket programming in objective-C right now and part of my code is giving me an error (in the setsockopt method call). I was wondering if anyone knows of a similar function to the GetLastError() function in C++ that I could use in objective-C to determine the problem with my code?

A:
You want to look at the value of errno
if the setsockopt
returns a negative value.
From setsockopt
manpage:
RETURN VALUE
Upon successful completion, setsockopt() returns 0. Otherwise, -1 is returned and errno is set to indicate the error.
You can see some standard errno
values here.
