+ * For full(er) information, see doc/heapprofile.html |
+ * |
+ * This module can be linked into your program with |
+ * no slowdown caused by this unless you activate the profiler |
+ * using one of the following methods: |
+ * |
+ * 1. Before starting the program, set the environment variable |
+ * "HEAPPROFILE" to be the name of the file to which the profile |
+ * data should be written. |
+ * |
+ * 2. Programmatically, start and stop the profiler using the |
+ * routines "HeapProfilerStart(filename)" and "HeapProfilerStop()". |
