Function RTInstallSharedIRQHandler

RTInstallSharedIRQHandler installs a high level interrupt handler on the specified IRQ and enables interrupts for that IRQ:

typedef void (RTTAPI * RTIntHandler)(void); 

void RTInstallSharedIRQHandler(int IRQ, 
                               RTIntHandler HighLevelHandler);

It is implemented through:

RTInstallSharedIRQHandlerEx(IRQ, (RTIntHandlerEx) HighLevelHandler, (void*)-1);

The return value of handlers installed with RTInstallSharedIRQHandler is ignored (assumed to be 0). Please see the documentation of RTInstallSharedIRQHandlerEx for details.
