DBM_PORT module routines

DBM_PORT module routines - WIN32

dbm_port.c - DeBug Message PORT routines

These routines allow a Windows app to send debug messages out transparently to its own operation. The messages are LAN broadcasted via UDP. The code supports four classes of debug messages and it is runtime configurable. If the debug level == 0 then the routines will do nothing but just return so this code can be left in final product code and activated on the customer box for tech support problem calls.

Warning about db_printf - it uses wvsprintf() which does not support floats & doubles. So if you need to output a floating point number you must first use sprintf to write it to a char buffer then you can dump the str from db_printf (sorry - but don't blame me - blame Bill and the boys).

Function	init_debug_port_subsystem
Include file	DBM_PORT.H
Prototype	void init_debug_port_subsystem( int debug_flag , int debug_port_num )
Remarks	Init the subsystem default values that will be used for the automatic port open.

Function	free_debug_port
Include file	DBM_PORT.H
Prototype	void free_debug_port( void )
Remarks	Force the debugg port closed and reset the global subsystem vars.

Function	open_debug_port
Include file	DBM_PORT.H
Prototype	void open_debug_port( void )
Remarks	Allocate and open a udp port to write the debug output to.

Function	db_printf
Include file	DBM_PORT.H
Prototype	void db_printf( int req_debug_level , const char *szFormat , ... )
Remarks	db_printf is a printf that outputs to a udp port if the requested debug level is set in the current debug_level. It will also handle the opening of the udp port if necessary.
