gprof
so, who knows how to get some useful info out of gprof's output? I've been
reading online docs, tinkering with the command line options, etc., but
have yet to find a combination that gives some useful stats. Sure, lots of
time is spent in low-level i/o, memory functions, but the call graph
doesn't show who's calling who very well. Are there certain files that
should not be compiled with -pg -a? Other tips?
thanks,
-Doug

Oh solaris... I'm not up on solaris gprofism. But yeah it sounds like
you're getting the right library. Make sure the -pg is on the link line
is all I can think of.
BTW, another dumb question, you are using the gmon.out from one of the
children and not the parent, right? :)

There's no libc_p on solaris, but according the manpages, the -pg flag will
cause the linker to use libc and libm in /usr/lib/libp/ which are the
profiling versions of each. So, libc_p and libp/libc are equivalents, I
assume.
What about useful command line option combos when running gprof?

Try linking with -lc_p ... Everything should be compiled -pg for the best
effect.
