Microsoft DirectX 8.1 (C++)

Structures

This section contains information on the following structures used with Microsoft® DirectInput®.

Note  The memory for all DirectX structures must be initialized to 0 before use. In addition, all structures that contain a dwSize member should set the member to the size of the structure, in bytes, before use. The following example performs these tasks on a common structure, DIDEVCAPS:

DIDEVCAPS didevcaps; // Can't use this yet
 
ZeroMemory(&didevcaps, sizeof(didevcaps));
didevcaps.dwSize = sizeof(didevcaps);
 
// Now the structure Can be used.
