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. BSD

NAME
psignal, strsignal, sys_siglist, sys_signame -- system signal messages LIBRARY
Standard C Library (libc, -lc) SYNOPSIS
#include <signal.h> void psignal(unsigned sig, const char *s); extern const char * const sys_siglist[]; extern const char * const sys_signame[]; #include <string.h> char * strsignal(int sig); DESCRIPTION
The psignal() and strsignal() functions locate the descriptive message string for a signal number. The strsignal() function accepts a signal number argument sig and returns a pointer to the corresponding message string. The psignal() function accepts a signal number argument sig and writes it to the standard error. If the argument s is non-NULL and does not point to the null character, s 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 message strings can be accessed directly through 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
