Structures

This section contains information on the following structures used with DirectInput:

• DICONDITION
• DICONSTANTFORCE
• DICUSTOMFORCE
• DIDATAFORMAT
• DIDEVCAPS
• DIDEVICEINSTANCE
• DIDEVICEOBJECTDATA
• DIDEVICEOBJECTINSTANCE
• DIEFFECT
• DIEFFECTINFO
• DIEFFESCAPE
• DIENVELOPE
• DIFILEEFFECT
• DIJOYSTATE
• DIJOYSTATE2
• DIMOUSESTATE
• DIMOUSESTATE2
• DIOBJECTDATAFORMAT
• DIPERIODIC
• DIPROPDWORD
• DIPROPGUIDANDPATH
• DIPROPHEADER
• DIPROPRANGE
• DIPROPSTRING
• DIRAMPFORCE

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.
