VC++宏

定義

#define VERIFY(exp) ASSERT(exp) 如果exp的值為真,繼續執行;否則中止。

在VC MFC中VERIFY有另一個意思,其是一個判斷的宏,MSDN中解釋如下:

In the debug version of MFC, the VERIFY macro evaluates its argument. If the result is 0, the macro prints a diagnostic message and halts the program. If the condition is nonzero, it does nothing.

The diagnostic message has the form

assertion failed in file <name> in line <num> where name is the name of the source file and num is the line number of the assertion that failed in the source file.

In the release version of MFC, VERIFY evaluates the expression but does not print or interrupt the program. For example, if the expression is a function call, the call will be made.

Example

VERIFY can be used for things that should never fail, though you may want to make sure you can provide better error recovery. if the error can actually cause a crash in a production system. It is possible that GetDC() may fail, but the out-of-memory condition that causes it isn't likely. For a test application, this use of VERIFY() is fine. For any production code, this usage is dubious.get the display device context HDC hdc; VERIFY( (hdc = ::GetDC(NULL)) != NULL);give the display context back ::ReleaseDC(hdc);
