Works exactly like the MFC macro TRACE1.
A format string as used in the run-time function printf.
The name of the variable whose value should be dumped.
See ISAPITRACE0 for a description of ISAPITRACE1.
ISAPI applications do not have to use MFC. If MFC is not linked to your application, ISAPITRACE1 provides the same TRACE1 functionality. If your application is linked to the MFC, ISAPITRACE1 simply calls MFC's TRACE1.
