PSIGNAL(3) FreeBSD 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.
