STDMETHOD
STDMETHOD is a macro used in C++ to declare function parameters for COM (Component Object Model) interfaces. COM is a binary standard for interfacing between different programming languages and operating systems, and it is commonly used in Windows programming. The macro is used to specify that a function takes a parameter that is an interface pointer.
The STDMETHOD macro is typically used in combination with the STDMETHODIMP macro, which is used to declare
STDMETHOD(FunctionName, [...] );
This macro takes two parameters: the name of the function and a list of parameter declarations. The
For example, when declaring a COM interface method that takes two string parameters and returns a result,
STDMETHODIMP MethodName(_In_ BSTR param1, _In_ BSTR param2)
_STDMETHODIMP is typically used to implement COM interfaces in Windows drivers and applications.
The STDMETHOD macro provides a way to specify the parameters of a COM interface method in a
The STDMETHOD macro is a part of the COM header files, and it is used in conjunction
