Get

XnStatus(* XnModuleGeneralIntInterface::Get) (XnModuleNodeHandle hGenerator, const XnChar *strCap, XnInt32 *pnValue)

Gets the current value of this capability

Parameters

hGenerator	[in] A handle to the instance
strCap	[in] Name of the capability
pnValue	[out] Current value

GetRange

XnStatus(* XnModuleGeneralIntInterface::GetRange) (XnModuleNodeHandle hGenerator, const XnChar *strCap, XnInt32 *pnMin, XnInt32 *pnMax, XnInt32 *pnStep, XnInt32 *pnDefault, XnBool *pbIsAutoSupported)

Gets the range of this capability values

Parameters

pnMin	[out] Minimum value
pnMax	[out] Maximum value
pnStep	[out] Step size
pnDefault	[out] Default value
pbIsAutoSupported	[out] TRUE if auto adjustment is supported, FALSE otherwise

RegisterToValueChange

XnStatus(* XnModuleGeneralIntInterface::RegisterToValueChange) (XnModuleNodeHandle hGenerator, const XnChar *strCap, XnModuleStateChangedHandler handler, void *pCookie, XnCallbackHandle *phCallback)

Registers a callback function to values changes.

Parameters

hGenerator	[in] A handle to the instance.
strCap	[in] Name of the capability
handler	[in] A pointer to a function that will be called when value changes.
pCookie	[in] A user cookie that will be passed to the callback function.
phCallback	[out] Optional. Will be filled with a handle to be passed to UnregisterFromValueChange().

Set

XnStatus(* XnModuleGeneralIntInterface::Set) (XnModuleNodeHandle hGenerator, const XnChar *strCap, XnInt32 nValue)

Sets the current value of this capability

Parameters

hGenerator	[in] A handle to the instance
strCap	[in] Name of the capability
nValue	[in] Value to set

UnregisterFromValueChange

void(* XnModuleGeneralIntInterface::UnregisterFromValueChange) (XnModuleNodeHandle hGenerator, const XnChar *strCap, XnCallbackHandle hCallback)

Unregisters a callback function which was registered using RegisterToValueChange().

Parameters

hGenerator	[in] A handle to the instance.
strCap	[in] Name of the capability
hCallback	[in] The handle to the callback returned from RegisterToValueChange().
