Parameters

handle module

The handle of the instance of the application that created the class. To obtain information about system defined classes (such as buttons or list boxes), this parameter should be set to null.

const character* name

An atom is a 16-bit integer value that is less than 0xc000. When an atom is specified for the class name, the high order part of this parameter must be set to zero.

window_class<character>* information

A pointer to a buffer to hold the class information being queried.
