Detailed Description

Provides an interface for handling SIGIO signals for input devices.

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.
