PSIGNAL(3)                386BSD Programmer's Manual                PSIGNAL(3)

NAME
     psignal, syssiglist - system signal messages

SYNOPSIS
     #include <sys/signal.h>

     void
     psignal(unsigned sig, const char *s)

     extern char *sys_siglist[];

DESCRIPTION
     The psignal() function locates the descriptive message string for the
     given signal sig number and writes it to the stderr.

     If the argument s is non-NULL it is written to the stderr prior to the
     message string.  The signal number should be from among those found in
     <signal.h>.

     The message strings can be accessed directly using the external character
     array sys_siglist. The defined variable NSIG contains a count of the
     messages in sys_siglist.

SEE ALSO
     sigaction(2),  perror(3)

HISTORY
     The psignal() function appeared in 4.2BSD.
