Function Documentation

void dmxSigioBlock (  void   )

Block SIGIO handling.

void dmxSigioDisableInput (  void   )

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

void dmxSigioEnableInput (  void   )

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

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.

void dmxSigioUnregister (  DMXInputInfo *  dmxInput  )

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