Note

The memory for all Microsoft 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.
