PSIGNAL(3)              NetBSD 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() func- tion, 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 abbrevia- tions 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.
