NetBSD 6.1.5 - man page for psignal (netbsd section 3)

PSIGNAL(3)			   BSD Library Functions Manual 		       PSIGNAL(3)

NAME
     psignal, psiginfo, sys_siglist, sys_signame -- system signal messages

LIBRARY
     Standard C Library (libc, -lc)

SYNOPSIS
     #include <signal.h>

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

     psiginfo(const siginfo_t *si, const char *s);

     extern const char * const sys_siglist[];
     extern const char * const sys_signame[];

DESCRIPTION
     The psignal() function locates the descriptive message string for the given signal number
     sig and writes it to the standard error.

     If the argument s is non-NULL it is written to the standard error file descriptor prior to
     the message string, immediately followed by a colon and a space.  If the signal number is
     not recognized (sigaction(2)), the string ``Unknown signal'' is produced.

     The psiginfo() function produces the same output as the psignal() function, only it uses the
     signal number information from the si argument.

     The message strings can be accessed directly using the external array sys_siglist, indexed
     by recognized signal numbers.  The external array sys_signame is used similarly and contains
     short, upper-case abbreviations for signals which are useful for recognizing signal names in
     user input.  The defined variable NSIG contains a count of the strings in sys_siglist and
     sys_signame.

SEE ALSO
     sigaction(2), perror(3), setlocale(3), strsignal(3)

HISTORY
     The psignal() function appeared in 4.2BSD.  The psiginfo() function appeared in NetBSD 6.0.
