NAME

       psignal - print signal message

SYNOPSIS

       #include <signal.h>

       void psignal(int sig, const char *s);

       extern const char *const sys_siglist[]

DESCRIPTION

       The psignal() function displays a message on stderr consisting of the string s, a colon, a space, and a string describing the signal number
       sig.  If sig is invalid, the message displayed will indicate an unknown signal.

       The array sys_siglist holds the signal description strings indexed by signal number.

RETURN VALUE

       The psignal() function returns no value.

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.
