Remarks

The SOM_TestC macro tests the specified boolean expression:

If the expression is TRUE and SOM_AssertLevel is set to a value greater than zero, then an information message is output.
If the expression is FALSE and SOM_WarnLevel is set to a value greater than zero, then a warning message is output.

Note: The SOM_Test macro is similar, except that it raises a fatal error in this situation.
