All the signal numbers are defined symbolically. For example, the
hangup signal is defined as \constant{signal.SIGHUP}; the variable names
are identical to the names used in C programs, as found in
- \file{<signal.h>}.
+ \code{<signal.h>}.
The \UNIX{} man page for `\cfunction{signal()}' lists the existing
signals (on some systems this is \manpage{signal}{2}, on others the
list is in \manpage{signal}{7}).
