found libpulse-dev and pulseaudio-libs
jcookeman, thanks for the lib names. I had looked for libpulse-dev in the installation manager and did not find it because I had misread it when I looked in "available" packages and it was already installed! (too much tv?)
libpulse-dev seems to be the library that I was looking for. I also installed pulseaudio-libs, though this is a "virtual" package that is included for backwards compatibility.
libpulse-dev includes the following:
/usr/lib: libpulse-browse.so, libpulse-mainloop-glib.so, libpulse-simple.so, libpulse.so
I plan to take a look at the documentation to see if that will be what will allow me to write the audio application in Linux. There were a few other pulseaudio libs that I also installed, and one is a plugin for audacious, an audio application for Linux that does some of the things that I was trying to do, so I can take a look at how they code parts of it (but they would be using different calls).
Any additional answers to the original post are of course welcome.
