NAME

psignal, sys_siglist − system signal messages

SYNOPSIS

/usr/ucb/cc [ flag ... ] file ...

void psignal (unsigned sig, char ∗s);

char ∗sys_siglist[];

DESCRIPTION

psignal() 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 NEWLINE.  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 sys_siglist 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 provided for in the table; it should be checked because new signals may be added to the system before they are added to the table.
