Some miscellaneous macros are provided, mainly for debug string processing. In particular, the NAME macro is used with many class constructors that support debug names. The REMIND macro is less useful; it just builds a reminder string (including the source file name and line number), which can be displayed at compile time.
Macro | Description |
NAME | Generates a debug-only name. |
REMIND | Generates a compile-time string. |
Generates a debug-only string.
NAME(
strLiteral
);
This macro is helpful for generating the debug name passed to many Microsoft® DirectShow™ class constructors. (See Object Register Debugging for more information about using that aspect of debugging.) For example:
x = new CVideoRenderer(NAME("Sample Video Renderer"),pUnk,phr);
The NAME macro generates NULL unless DEBUG is defined when the Microsoft DirectShow headers are included.
Generates a compile-time string.
REMIND(
strLiteral
);
This generated string includes the parameter string, the source file name, and the line number.
For example, to generate a compile-time warning, use the following syntax.
#pragma message (REMIND("Add automation support"))
