* MODULE: debug.h

|
|
* Header file for (debug.cxx).
|
||
|
|
*
|
||
|
|
* Double braces are needed for output macros.
|
||
|
|
*
|
||
|
|
* DBGMSG(DBG_LEV_ERROR, ("Error code %d", Error));
|
||
|
|
*
|
||
|
|
* This is because we can't use variable parameter lists in macros.
|
||
|
|
* The statement gets pre-processed to a semi-colon in non-debug mode.
|
||
|
|
*
|
||
|
|
* Set the global variable GLOBAL_DEBUG_FLAGS via the debugger.
|
||
|
|
* Setting the flag in the low word causes that level to be printed;
|
||
|
|
* setting the high word causes a break into the debugger.
|
||
|
|
* E.g. setting it to 0x00040006 will print out all warning and error
|
||
|
|
* messages, and break on errors.
