Display the C ++ debugging information in the vs output window and call it like a trace.

We know that MFC can call macro trace and other very convenient output debugging information to the Visual Studio output window, but there is no human-like function in C ++. Recently I am developing a smallProgramWe tracked the trace macro of MFC and found that it is mapped to the atltrace macro in atltrace. H. for some reasons, we also want to use trace in C ++ as follows:

# Include <atltrace. h>
# Define trace atltrace

Trace ("");

In C ++, you can directly use the following functions:
