raise -- send signal to program

Synopsis

   #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(2) for a list of signals.

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