PSIGNAL(3)                 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.
