/* * "showmem.c" A C Norman, January 1996-2002 * * This program processes a "memory.use" log file created by CSL * in a variant compiled with MEMORY_TRACE defined. It displays the * memory use map and allows the user to zoom in using I and out using * O, move left, right, up or down. V redraws viewing just the box. * A "." input resets the image. The numbers displayed at the top left * are as for use with "-m" in a CSL command line to provoke an exception * when a memory reference in the box is first seen. * * This code uses the Watcom graphics library, so is DOS specific. Furthermore * it is coded assuming you have a monitor suitable for 1024*768 in * 256 colours. */ /* * This code may be used and modified, and redistributed in binary * or source form, subject to the "CCL Public License", which should * accompany it.
