TRACE0

TRACE0( exp )

Parameters

exp

A format string as used in the run-time function printf.

Remarks

TRACE0 is similar to TRACE, and is one variant of a group of trace macros that you can use for debug output. The group includes:

• TRACE0 - Takes a format string (Only) and can be used for simple text messages which are dumped to afxDump
  
  
• TRACE1 - Takes a format string plus one argument (one variable which is dumped to afxDump)
  
  
• TRACE2 - Takes a format string plus two arguments (two variables which are dumped to afxDump)
  
  
• TRACE3 - Takes a format string plus three arguments (three variables which are dumped to afxDump)

TRACE0 does nothing if you have compiled a release version of your application. As with TRACE, it only dumps data to afxDump if you have compiled a debug version of your application.

Note   This macro is available only in the debug version of MFC.

Example

// example for TRACE0
TRACE0( "Start Dump of MyClass members:" );
