-.SH DESCRIPTION
-The
-.BR err ()
-and
-.BR warn ()
-family of functions display a formatted error message on the standard
-error output.
-In all cases, the last component of the program name, a colon character,
-and a space are output.
-If the
-.I fmt
-argument is not NULL, the
-.BR printf (3)-like
-formatted error message is output.
-The output is terminated by a newline character.
-.P
-The
-.BR err (),
-.BR verr (),
-.BR warn (),
-and
-.BR vwarn ()
-functions append an error message obtained from
-.BR strerror (3)
-based on the global variable
-.IR errno ,
-preceded by another colon and space unless the
-.I fmt
-argument is
-NULL.
-.P
-The
-.BR errx ()
-and
-.BR warnx ()
-functions do not append an error message.
-.P
-The
-.BR err (),
-.BR verr (),
-.BR errx (),
-and
-.BR verrx ()
-functions do not return, but exit with the value of the argument
-.IR eval .
