NAME    [Toc]    [Back]

     psignal, psiginfo - system	signal messages

SYNOPSIS    [Toc]    [Back]

     #include <siginfo.h>

     void psignal (int sig, const char *s);

     void psiginfo (siginfo_t *pinfo, const char *s);

DESCRIPTION    [Toc]    [Back]

     psignal and psiginfo produce messages on the standard error output
     describing	a signal.  sig is a signal that	may have been passed as	the
     first argument to a signal	handler.  pinfo	is a pointer to	a siginfo
     structure that may	have been passed as the	second argument	to an enhanced
     signal handler [see sigaction(2)].	 The argument string s is printed
     first, then a colon and a blank, then the message and a newline. Most
     usefully, the argument string is the name of the program which incurred
     the signal.  The signal number should be from among those found in
     <signal.h>.
