# Makefile for zlib
# Copyright (C) 1995-2017 Jean-loup Gailly, Mark Adler
# For conditions of distribution and use, see copyright notice in zlib.h
# To compile and test, type:
# ./configure; make test
# Normally configure builds both a static and a shared library.
# If you want to build just a static library, use: ./configure --static
# To use the asm code, type:
# cp contrib/asm?86/match.S ./match.S
# make LOC=-DASMV OBJA=match.o
# To install /usr/local/lib/libz.* and /usr/local/include/zlib.h, type:
# make install
# To install in $HOME instead of /usr/local, use:
# make install prefix=$HOME

This BYFOUR code accesses the passed unsigned char * buffer with a 32-bit
integer pointer type. This violates the strict aliasing rule, where a
compiler can assume, for optimization purposes, that two pointers to
fundamentally different types won't ever point to the same memory. This can
manifest as a problem only if one of the pointers is written to. This code
only reads from those pointers. So long as this code remains isolated in
this compilation unit, there won't be a problem. For this reason, this code
should not be copied and pasted into a compilation unit in which other code
writes to the buffer that is passed to these routines.

/* ===========================================================================
Decompresses the source buffer into the destination buffer. *sourceLen is
the byte length of the source buffer. Upon entry, *destLen is the total size
of the destination buffer, which must be large enough to hold the entire
uncompressed data. (The size of the uncompressed data must have been saved
previously by the compressor and transmitted to the decompressor by some
mechanism outside the scope of this compression library.) Upon exit,
*destLen is the size of the decompressed data and *sourceLen is the number
of source bytes consumed. Upon return, source + *sourceLen points to the
first unused input byte.
uncompress returns Z_OK if success, Z_MEM_ERROR if there was not enough
memory, Z_BUF_ERROR if there was not enough room in the output buffer, or
Z_DATA_ERROR if the input data was corrupted, including if the input data is
an incomplete zlib stream.
