Can profiling do this?

[Davy Durham <david dot durham at wcom dot com>]

    I'm trying to profile an application "-p" flag...    I'd really like

to be able to call a function in the code that would say, start or stop
the profiling..

   See, the processing in my app is broken into several phases, and one
of the phases is taking a bit too long and I want to try to optimize
it.... Hence, I don't want the other phases' information to be included
in gprof's output...

    Perhaps this is a gprof issue?


Thanks,
    Davy
