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, lower-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), strerror(3) HISTORY
The psignal() function appeared in 4.2BSD. BSD
February 27, 1995 BSD
