+.SH DESCRIPTION
+The
+.BR psignal ()
+function displays a message on \fIstderr\fP
+consisting of the string \fIs\fP, a colon, a space, a string
+describing the signal number \fIsig\fP, and a trailing newline.
+If the string \fIs\fP is NULL or empty, the colon and space are omitted.
+If \fIsig\fP is invalid,
+the message displayed will indicate an unknown signal.
+.PP
+The
+.BR psiginfo ()
+function is like
+.BR psignal (),
+except that it displays information about the signal described by
+.IR pinfo ,
+which should point to a valid
+.I siginfo_t
+structure.
+As well as the signal description,
+.BR psiginfo ()
+displays information about the origin of the signal,
+and other information relevant to the signal
+(e.g., the relevant memory address for hardware-generated signals,
+the child process ID for
+.BR SIGCHLD ,
+and the user ID and process ID of the sender, for signals set using
+.BR kill (2)
+or
+.BR sigqueue (3)).
+.SH RETURN VALUE
+The
+.BR psignal ()
+and
+.BR psiginfo ()
+functions return no value.
