- Description
The EnumObjects() method will enumerate the individual input and force feedback objects of a device.
Error values that can be generated are:
DIERR_INVALIDPARAM
DIERR_NOTINITIALIZED
- Parameters
ReferenceData
The ReferenceData parameter defines context or reference data to be passed to the callback function each time it is called.
Flags
The Flags parameter defines flags indicating which object types are to be enumerated.
The described effect applies when the flag is set.
Objects matching any of the flags set will be enumerated unless DIDFT_FFACTUATOR or DIDFT_FFEFFECTTRIGGER is present, in which case enumeration is limited to objects matching all the set flags values.
