I've been doing some more C coding lately, and have some questions.

First is there any standardized way of parsing command line inputs to a C
program.  I rummaged around the C standard looking for some magic library
that makes command line input parsing not suck, but there isn't anything.
Is there some well used external library I can grab and use to ease command
line input parsing in C programs?

Second why is signal.h and signal handling in general part of the C
standard?  C is a generic platform independent language.  It is surprising
to me that something as UNIX specific as signals is part of ANSI C.  Is the
notion of signals more widespread then I thought, or is this just a
historical artifact related to C's heritage as the UNIX systems programming
language?
