/*
 * This file defines mtrace() and muntrace(), two functions which enable
 * and disable memory allocation tracing respectively.  These should be
 * called in matching pairs but will have no effect unless the MALLOC_TRACE
 * environment variable is set to the filename of the trace file to use.
 * The resulting trace files can be processed by the mtrace perl script
 * which is distributed with the GNU C library.
