-.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.
