KASSERT macro

  • Article

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Evaluates an expression, and causes a breakpoint exception if the expression is FALSE. The text of the expression, the name of the source file, and the line number are logged using the DbgLog macro. Ignored in retail builds.

Syntax

void KASSERT(
    cond
);

Parameters

cond

Expression to evaluate.

Return value

This macro does not return a value.

Remarks

Unlike the ASSERT and EXECUTE_ASSERT macros, this macro does not display a message box prompting the user. In debug builds, if the expression is FALSE, the macro automatically causes a breakpoint exception to occur.

Requirements

Requirement Value
Header
Wxdebug.h (include Streams.h)
