Thanks Bakunin! That helps a lot.
"You seem to not understand how executable code is produced from source code." Have some ideas about it, but not much practical experience.Never tried dissection of the executable code from source code. However, this is not what I want to learn.

That is: which data it expects and what it gives back. That fits exactly what I'm struggling with, as I know the raw data I have at hand and what I expect to get with the raw data.Believe this is all the programs do.

you "need" the header filles and the library itself. Of course you need to know what the functions do, so some text documentation is also necessary. This gives me more information on my question. I need more practice to get my feet wet, and soaked!

Thank you all for the replies!

libbz2(3)						     Library Functions Manual							 libbz2(3)

NAME

       libbz2 - library for block-sorting data compression

SYNOPSIS

       cc [ flag ...] file..."	-lbz2 [ library ... ]

       #include <stdio.h>
       #include <bzlib.h>

DESCRIPTION

       Interfaces  in  this library provide the ability to compress (and decompress) files using the Burrows-Wheeler blocksorting text compression
       algorithm, and  Huffman	coding. It is provided along with the bzip2(1) utility.  See bzip2(1) for more information.

       The source distribution of bzip2 contains a description of how to use this library in HTML form.

       For additional information on shared object interfaces,	see intro(3).

       The ideas embodied in bzip2 are due to (at least) the fol- lowing people: Michael Burrows  and  David  Wheeler  (for   the  block   sorting
       transformation),  David	Wheeler (again, for the Huffman coder), Peter Fenwick (for the structured cod- ing model in the original bzip, and
       many refinements), and Alistair Moffat, Radford Neal  and  Ian  Witten  (for  the arithmetic  coder  in	 the   original   bzip).    I	am
       much  indebted  for their help, support and advice.  See the man- ual  in the source distribution for pointers to sources of documentation.
       Christian von Roques encouraged me to look for  faster sorting algorithms, so as to speed up compres- sion.  Bela Lubkin encouraged  me	to
       improve	the  worst-case  compression  performance.  Many people sent patches, helped with portability problems, lent machines, gave advice
       and were generally helpful.
