Structures

This section contains reference information for the following structures used with DirectSound:

• DS3DBUFFER
• DS3DLISTENER
• DSBCAPS
• DSBPOSITIONNOTIFY
• DSBUFFERDESC
• DSBUFFERDESC1
• DSCAPS
• DSCBCAPS
• DSCBUFFERDESC
• DSCCAPS

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

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