RETAILMSG
A version of this page is also available for

This macro conditionally outputs a printf-style formatted message.
Syntax
RETAILMSG (
Expression,
Message
)
Parameters
- Expression
Boolean expression used to determine if the message would be output.
- Message
Expression to be printed using printf format style.
Return Value
None.
Remarks
The printf-style message parameter is output if the Boolean input expression evaluates to TRUE. Note that the parameter Message must be enclosed by parentheses to prevent syntax errors being generated by the preprocessor. This macro should be used sparingly, as it increases the size of retail builds.
Example
RETAILMSG(TRUE, (TEXT("Testing item count against maximum %u\r\n"),
dwMaxNumberOfItems));
RETAILMSG(dwCurrentNumberOfItems >= dwMaxNumberOfItems,
(TEXT("Invalid item count! Found %u, expected less than %u\r\n"),
dwCurrentNumberOfItems, dwMaxNumberOfItems));
Output:
Testing item count against maximum 68
Invalid item count! Found 343, expected less than 68
