    Command:

    gsignal

    
    
    

    SYNOPSIS

           #include <signal.h>
    
           typedef void (*sighandler_t)(int);
    
           int gsignal(int signum);
    
           sighandler_t ssignal(int signum, sighandler_t action);
    
       Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
    
           gsignal(), ssignal(): _SVID_SOURCE
    
    
    

    DESCRIPTION

           Don't  use  these  functions under Linux.  Due to a historical mistake,
           under Linux these functions are aliases  for  raise(3)  and  signal(2),
           respectively.
    
           Elsewhere, on System V-like systems, these functions implement software
           signaling, entirely independent of the classical signal(2) and  kill(2)
           functions.   The function ssignal() defines the action to take when the
           software signal with number signum is raised using the  function  gsig-
           nal(),  and  returns the previous such action or SIG_DFL.  The function
           gsignal() does the following: if no action (or the action SIG_DFL)  was
           specified  for  signum,  then  it  does  nothing and returns 0.  If the
           action SIG_IGN was specified for  signum,  then  it  does  nothing  and
           returns  1.   Otherwise,  it resets the action to SIG_DFL and calls the
           action function with argument signum, and returns the value returned by
           that  function.  The range of possible values signum varies (often 1-15
           or 1-17).
    
    
    

    CONFORMING TO

           These functions are available under AIX, DG/UX,  HP-UX,  SCO,  Solaris,
           Tru64.   They  are called obsolete under most of these systems, and are
           broken under Linux libc and glibc.  Some systems also have  gsignal_r()
           and ssignal_r().
