flashupdate_proc
Syntax
MVICALLBACK flashupdate_proc( );
Parameters
None
Description
flashupdate_proc is an optional callback function which may be passed to the
CIP API in the MVIcip_RegisterFlashUpdateRtn call. If the flashupdate_proc
callback has been registered, it will be called if the backplane device driver
receives a flash update command. This allows the application an opportunity to
take appropriate actions before it is stopped.
Return Value
The flashupdate_proc routine must return MVI_SUCCESS.
Example
MVIHANDLE Handle;
MVICALLBACK flashupdate_proc( void )
{
// Take whatever action is appropriate for the application:
// - Set local I/O to safe state
// - Trigger an orderly shutdown
return(MVI_SUCCESS);
}
