fatalfault_proc

Syntax

OCXCALLBACK fatalfault_proc( );

Parameters

None

Description

fatalfault_proc is an optional callback function which may be passed to the CIP

API in the OCXcip_RegisterFatalFaultRtn call. If the fatalfault_proc callback

has been registered, it will be called if the backplane device driver detects a fatal

fault condition. This allows the application an opportunity to take appropriate

actions.

Return Value

The fatalfault_proc routine must return OCX_SUCCESS.

Example

OCXHANDLE Handle;

OCXCALLBACK fatalfault_proc( void )

{

// Take whatever action is appropriate for the application:

// - Set local I/O to safe state

// - Log error

// - Attempt recovery (for example, restart module)

return(OCX_SUCCESS);

}
