/* FUNCTION: settrapsize()
 *
 * settrapsize() - This sets a value which will cause the memory 
 * managment monitoring code to trap to a debugger if a malloc is 
 * attempted for this size. This is usefull when a memory leak is 
 * occuring of memory buffers on an unusual size, as often happens 
 * with networking code. It has nothing to do with SNMP traps. 
 * Returns no meaningfull value; declared as int to make compiler 
 * happy. 
 *
 * 
 * PARAM1: void * pio   - output stream
 *
 * RETURNS: 0
