Subject:	What are these weird functions?
Mime-Version:	1.0

                              
HI.
I downloaded the zlib_pc library so that I can read .z files directly in my
programs instead of unpacking them using compress -d ...
I built the library w/o any problem.  When I linked it to my program, I got
errors on unknown external symbols halloc and hfree.  I grep'ed the zlib_pc
sources and found halloc and hfree.  The calls looked similar to calloc and
free, so I changed it and it worked!  I still am curious about halloc and
hfree.  What are they supposed to be?  I couldn't find any C book which talks
about these functions.  Are they the remnants of some bygone era or
something?

Ciao
