LIBRARY

     Standard C Library (libc, -lc)

SYNOPSIS

     #include <signal.h>

     int
     raise(int sig);

DESCRIPTION

     The raise() function sends the signal sig to the current thread.

RETURN VALUES

     The raise() function returns the value 0 if successful; otherwise the value -1 is returned and the global variable errno is set to indicate
     the error.

ERRORS

     The raise() function may fail and set errno for any of the errors specified for the library functions getpid(2) and pthread_kill(2).

SEE ALSO

     kill(2), pthread_kill(2)

STANDARDS

     The raise() function conforms to ISO/IEC 9899:1990 (``ISO C90'').

NAME

       raise - Sends a signal to the executing process or thread

LIBRARY

       Standard C Library (libc.so, libc.a)

SYNOPSIS

       #include <signal.h>

       int raise(
	       int signal );

STANDARDS

       Interfaces documented on this reference page conform to industry standards as follows:

       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.
