Function Documentation

int dmxAddInput	(	DMXInputAttributesPtr	attr,
		int *	id
	)

Add an input with the specified attributes. If the input is added, the physical id is returned in deviceId.

int dmxAttachScreen	(	int	idx,
		DMXScreenAttributesPtr	attr
	)

Reattach previously detached back-end screen.

int dmxGetInputAttributes	(	int	deviceId,
		DMXInputAttributesPtr	attr
	)

Return information about the device with id = deviceId. This information is primarily for the ProcDMXGetInputAttributes() function, which does not have access to the appropriate data structure.

int dmxGetInputCount

(

void

)

Return the total number of devices, not just dmxNumInputs. The number returned should be the same as that returned by XListInputDevices.

References dmxInputs, and dmxNumInputs.

Referenced by dmxInputLogDevices(), and ProcDMXGetInputCount().

unsigned long dmxGetNumScreens

(

void

)

Return the value of dmxNumScreens -- the total number of backend screens in use (these are logical screens and may be larger than the number of backend displays).

References dmxNumScreens.

Bool dmxGetScreenAttributes	(	int	physical,
