Is there anyway an interrupt can be sent to a program whenever a message
intended for it arrives on a socket?Is there a standard signal available in
Berkeley 4.2 BSD Unix for such an interrupt ?Basically I do not want to wait
on a recvfrom call.At the same time I would like to handle any messages.(A recvfrom call with a non blocking option set doesn't help as it returns an error
E_WOULDBLOCK if there are no messages when the recvfom is executed).Any pointers will be appreciated.
