Summary

Sends a message to the debugger including location information.

Pascal

 procedure TraceLoc(const Msg: string);

Parameters

Parameters	Description
const Msg: string	The message to send to the debugger.

Description

TraceLoc sends the specified message to the debugger but first prepends it with the source file location from which TraceLoc is called. For example, when calling TraceLoc from a method called TForm1.Button1Click located in unit1.pas like this: TraceLoc('Trace me.') the resulting string sent to the debugger will be: unit.pas:123 (TForm1.ButtonClick) "Trace me." assuming the TraceLoc statement is on line 123 in the source. Note that this function requires a detailed map file!

Notes

If you are running your application under the control of the debugger you can view these messages using the event log dialog, 'View | Debug Windows | Event Log'. If the application is not running under the debugger the message is sent to the system debugger. If there is no system debugger active the function does nothing.
