 .SH DESCRIPTION
 The
 .BR psignal ()
 function displays a message on \fIstderr\fP
-consisting of the string \fIs\fP, a colon, a space, and a string
-describing the signal number \fIsig\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 (2)).
+
 The array \fIsys_siglist\fP holds the signal description strings
 indexed by signal number.
 .SH "RETURN VALUE"
 The
 .BR psignal ()
-function returns no value.
+and
+.BR psiginfo ()
+functions return no value.
+.SH VERSIONS
+The
+.BR psiginfo()
+function was added to glibc in version 2.10.
 .SH "CONFORMING TO"
 POSIX.1-2008, 4.3BSD.
+.SH BUGS
+In glibc versions up to 2.12,
+.BR psiginfo ()
+had the following bugs:

+In some circumstances, a trailing newline is not printed.
