NAME

raise − send signal to program

#include <signal.h>

int raise(int sig);

raise() sends the signal sig to the executing program.

raise() uses kill() to send the signal to the executing program:

kill(getpid(), sig);

See kill(2) for a detailed list of failure conditions. See signal(3C) for a list of signals.

raise() returns zero if the operation succeeds. Otherwise, raise() returns −1 and errno is set to indicate the error.
