The TRACE macros are obsolete, use ATLTRACE2.
See TRACE0 for a description of the TRACE1 macro.
- exp
A format string as used in the run-time function printf.
- param1
The name of the variable whose value should be dumped.
// Example for TRACE1
int i = 1;
TRACE1( "Integer = %d\n", i );
// Output: 'Integer = 1'
// Another example for TRACE1
DWORD dwLastError = ::GetLastError();
TRACE1("The last error code for this thread is %d\n", dwLastError);
