Now the tdsignal function accepts both proc pointer and thread pointer, if thread pointer is NULL, tdsignal automatically finds a thread, otherwise it sends signal to given thread. Add utility function psignal_event to send a realtime sigevent to a process according to the delivery requirement specified in struct sigevent. END
