The basic concept of signal Each signal has a number and a macro definition name that can be signal.h found in. Use the kill -l command to view the list of signals defined in the system: 1-31 is a normal signal; 34-64 is a live signal. All signals are sent by the operating system! Three ways to handle a signal 1, ignore this signal: most of the signal can be used in this way to deal with, but there are two kinds of signals must not be ignored. They are: SIGKILL and SIGSTOP .
