stop reasons are not a property of the whole process, but of a
particular thread (after all, you can have multiple threads stopping
at the same time for different (or same) reasons). So, to get the stop
reason, you first need to enumerate all the threads of the process
(SBProcess::GetThreadAtIndex) and then ask each thread for it's stop
reason (SBThread::GetStopReason). If the stop reason is
eStopReasonSignaled, then SBThread::GetStopReasonDataAtIndex(0) will
give you the signal number.
