       psignal, sys_siglist - system signal messages

       void psignal(sig, s)
       unsigned sig;
       char *s;

       char *sys_siglist[];

       The  subroutine	produces  a  short  message  on  the  standard error file describing the indicated signal.  First the argument string s is
       printed, then a colon, then the name of the signal and a new-line.  Most usefully, the argument string is the name  of  the  program  which
       incurred the signal.  The signal number should be from among those found in <signal.h>.

       To  simplify  variant  formatting of signal names, the vector of message strings is provided.  The signal number can be used as an index in
       this table to get the signal name without the newline.  The define NSIG defined in <signal.h> is the number of messages.

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
