DirectDraw Structures

This section contains information about the following structures used with DirectDraw:

Note  You should initialize the memory for each DirectX structure to 0 before you use the structure. In addition, for all structures that contain a dwSize member, you should set the member to the size of the structure, in bytes, before the structure is used. The following example performs these tasks on a common structure, DDCAPS:



DDCAPS ddcaps; // You cannot use this yet.
 
ZeroMemory(&ddcaps, sizeof(DDCAPS));
ddcaps.dwSize = sizeof(DDCAPS);
 
// Now you can use the structure.
.
