-
-DESCRIPTION
-Send the signal <[sig]> (one of the macros from `<<sys/signal.h>>').
-This interrupts your program's normal flow of execution, and allows a signal
-handler (if you've defined one, using <<signal>>) to take control.
-
-The alternate function <<_raise_r>> is a reentrant version.  The extra
-argument <[reent]> is a pointer to a reentrancy structure.
-
-RETURNS
-The result is <<0>> if <[sig]> was successfully raised, <<1>>
-otherwise.  However, the return value (since it depends on the normal
-flow of execution) may not be visible, unless the signal handler for
-<[sig]> terminates with a <<return>> or unless <<SIG_IGN>> is in
-effect for this signal.
-
-PORTABILITY
-ANSI C requires <<raise>>, but allows the full set of signal numbers
-to vary from one implementation to another.
-
-Required OS subroutines: <<getpid>>, <<kill>>.

-
-DESCRIPTION
-<<signal>> provides a simple signal-handling implementation for embedded
-targets.
-
-<<signal>> allows you to request changed treatment for a particular
-signal <[sig]>.  You can use one of the predefined macros <<SIG_DFL>>
-(select system default handling) or <<SIG_IGN>> (ignore this signal)
-as the value of <[func]>; otherwise, <[func]> is a function pointer
-that identifies a subroutine in your program as the handler for this signal.
-
-Some of the execution environment for signal handlers is
-unpredictable; notably, the only library function required to work
-correctly from within a signal handler is <<signal>> itself, and
-only when used to redefine the handler for the current signal value.
-
-Static storage is likewise unreliable for signal handlers, with one
-exception: if you declare a static storage location as `<<volatile
-sig_atomic_t>>', then you may use that location in a signal handler to
-store signal values.
-
-If your signal handler terminates using <<return>> (or implicit
-return), your program's execution continues at the point
-where it was when the signal was raised (whether by your program
-itself, or by an external event).  Signal handlers can also
-use functions such as <<exit>> and <<abort>> to avoid returning.
-
-The alternate function <<_signal_r>> is the reentrant version.
-The extra argument <[reent]> is a pointer to a reentrancy structure.
-
-@c FIXME: do we have setjmp.h and assoc fns?
-
-RETURNS
-If your request for a signal handler cannot be honored, the result is
-<<SIG_ERR>>; a specific error number is also recorded in <<errno>>.
-
-Otherwise, the result is the previous handler (a function pointer or
-one of the predefined macros).
-
-PORTABILITY
-ANSI C requires <<signal>>.
-
-No supporting OS subroutines are required to link with <<signal>>, but
-it will not have any useful effects, except for software generated signals,
-without an operating system that can actually raise exceptions.

-@chapter Signal Handling (@file{signal.h})
-
-A @dfn{signal} is an event that interrupts the normal flow of control
-in your program.  Your operating environment normally defines the full
-set of signals available (see @file{sys/signal.h}), as well as the
-default means of dealing with them---typically, either printing an
-error message and aborting your program, or ignoring the signal.
-
-All systems support at least the following signals:
-@table @code
-@item SIGABRT
-Abnormal termination of a program; raised by the <<abort>> function.
-
-@item SIGFPE
-A domain error in arithmetic, such as overflow, or division by zero.
-
-@item SIGILL
-Attempt to execute as a function data that is not executable.
-
-@item SIGINT
-Interrupt; an interactive attention signal.
-
-@item SIGSEGV
-An attempt to access a memory location that is not available.
-
-@item SIGTERM
-A request that your program end execution.
-@end table
-
-Two functions are available for dealing with asynchronous
-signals---one to allow your program to send signals to itself (this is
-called @dfn{raising} a signal), and one to specify subroutines (called
-@dfn{handlers} to handle particular signals that you anticipate may
-occur---whether raised by your own program or the operating environment.
-
-To support these functions, @file{signal.h} defines three macros:
-
-@table @code
-@item SIG_DFL
-Used with the @code{signal} function in place of a pointer to a
-handler subroutine, to select the operating environment's default
-handling of a signal.
-
-@item SIG_IGN
-Used with the @code{signal} function in place of a pointer to a
-handler, to ignore a particular signal.
-
-@item SIG_ERR
-Returned by the @code{signal} function in place of a pointer to a
-handler, to indicate that your request to set up a handler could not
-be honored for some reason.
-@end table
-
-@file{signal.h} also defines an integral type, @code{sig_atomic_t}.
-This type is not used in any function declarations; it exists only to
-allow your signal handlers to declare a static storage location where
-they may store a signal value.  (Static storage is not otherwise
-reliable from signal handlers.)
