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(): XSH5.0
Refer to the standards(5) reference page for more information about industry standards and associated tags.
PARAMETERS
Specifies a signal number.
DESCRIPTION
The raise() function sends the signal specified by the signal parameter to the invoking thread. In single-threaded programs this is equiva-
lent to:
kill(getpid(), signal);
The behavior of the raise() function is equivalent to:
pthread_kill(pthread_self(), signal);
RETURN VALUES
Upon successful completion of the raise() function, a value of 0 (zero) is returned. Otherwise, a nonzero value is returned and errno is
set to indicate the error.
ERRORS
The raise() function sets errno to the specified values for the following conditions: The value of the signal parameter is an invalid sig-
nal number.

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.'
