void dmxSigioBlock

(

void

)

Block SIGIO handling.

Referenced by dmxCoreMotion(), dmxExtMotion(), and dmxTranslateAndEnqueueExtEvent().

void dmxSigioDisableInput

(

void

)

Disable SIGIO handling. This removes the hanlder from the OS.

References dmxInputEnabled, dmxInputs, dmxNumInputs, and dmxSigioRemove().

Referenced by dmxWakeupHandler().

void dmxSigioEnableInput

(

void

)

Enable SIGIO handling. This instantiates the handler with the OS.

References dmxInputEnabled, dmxInputs, dmxNumInputs, and dmxSigioAdd().

Referenced by dmxSwitchReturn().

void dmxSigioRegister	(	DMXInputInfo *	dmxInput,
		int	fd
	)

Make a note that the input device described in dmxInput will be using the file descriptor fd for SIGIO signals. Calls AddEnabledDevice ifi SIGIO handling has been enabled with dmxSigioEnableInput().

void dmxSigioUnblock

(

void

)

Unblock SIGIO handling.

Referenced by dmxCoreMotion(), dmxExtMotion(), and dmxTranslateAndEnqueueExtEvent().

void dmxSigioUnregister

(

DMXInputInfo *

dmxInput

)

Remove the notes that dmxInput is using any file descriptors for SIGIO signals. Calls RemoveEnabledDevice.
