fatalfault_proc
Syntax
MVICALLBACK fatalfault_proc( );
Parameters
None
Description
fatalfault_proc is an optional callback function which may be passed to the CIP
API in the MVIcip_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 MVI_SUCCESS.
Example
MVIHANDLE Handle;
MVICALLBACK 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(MVI_SUCCESS);
}
