<unistd.h> not giving me getopt in C

Name: Anonymous 2011-03-04 6:28

So I am writing a program using C which implements options. Naturally I'd need to #include <unistd.h>. However after including this header file, I still get the error:

undefined symbol: opterr
warning: implicit function declaration: getopt

etc. wat do /prog/?

Thanks for the sage, but now it just opened up a ton more errors. It did help though, so thank you. /prog/ shouldn't do my homework but I need help.

Thanks for the sage
If you'd have lurked /prog/ a bit before selfishly posting yet another boring HALP thread; you would have realized saging is considered polite here.
