Alloc.h

/*
 *      Alloc.h - memory allocation module header
 *
 *  DESCRIPTION
 *      This header contains macros that replace the standard C memory 
 *      allocation routines.  They throw an exception when there is not
 *      enough memory.  The macros use functions defined in "Alloc.c".
 *      The handy new() macro is added; it only needs the type name.
 *
 *      Using macros allows the file name and line number information supplied
 *      by the preprocessor, to be available for error reporting.
 *
 *  COPYRIGHT
 *      You are free to use, copy or modify this software at your own risk.
