raise(3C)raise(3C)NAME
raise - send a signal to the executing thread
SYNOPSIS
#include <signal.h>
int raise(int sig);
The raise() function sends the signal sig to the executing thread. If a signal handler is called, the raise function does not return until
after the signal handler returns.
The effect of the raise function is equivalent to calling:
pthread_kill(pthread_self(), sig);
See the pthread_kill(3C) manual page for a detailed list of failure conditions and the signal.h(3HEAD) manual page for a list of signals.
Upon successful completion, 0 is returned. Otherwise, -1 is returned and errno is set to indicate the error.

raise - send a signal to the caller
SYNOPSIS
#include <signal.h>
int raise(int sig);
DESCRIPTION
The raise() function sends a signal to the calling process or thread. In a single-threaded program it is equivalent to
kill(getpid(), sig);
In a multithreaded program it is equivalent to
pthread_kill(pthread_self(), sig);
If the signal causes a handler to be called, raise() will only return after the signal handler has returned.
RETURN VALUE
raise() returns 0 on success, and nonzero for failure.

I am trying to send a SIGUSR1 to a set of process. Please tell
me how to do. I've tried the system call raise(int sig) but it just
raise a signal of to the 'current process.'
