ValidateStringPtrW

Verifies that the calling process has read access to a wide-character string. If not, the macro calls the DbgBreak macro.

Syntax

ValidateStringPtrW(
    LPCWSTR p
);

Parameters

p

Pointer to a NULL-terminated wide-character string.

Remarks

This macro is ignored unless DEBUG, _DEBUG, or VFWROBUST is defined when the DirectShow base-class header file is included. This macro can have a significant performance cost.
