MacMemory.c
This is meant to be used in association with MacMemory.h, which redefines the
Standard C memory allocation functions to be implemented directly as calls to
the Macintosh Memory Manager. So don't write programs that explicitly call
"MacRealloc". This is for portable C programs that call "realloc", but which
will be compiled to use MacRealloc instead, for best performance on the Mac.
You use MacMemory.h by adding the line
#include "MacMemory.h"
either to your THINK/CodeWarrior C project prefix or to some header file that you
include in all your files.
HISTORY:
10/25/94 dgp deleted MacMemset() because it's no longer needed. CodeWarrior 4.5 works fine.
