They are intended to indicate +exceptional events, like a user pressing the interrupt key on his +terminal, or a network connection being broken. There is a class of +signals that can be sent to the process currently reading input from +the keyboard. Since Readline changes the terminal attributes when it +is called, it needs to perform special processing when a signal is +received to restore the terminal to a sane state, or provide application +writers with functions to do so manually. + +Readline contains an internal signal handler that is installed for a +number of signals (@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, +@code{SIGALRM}, @code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}). +When one of these signals is received, the signal handler +will reset the terminal attributes to those that were in effect before +@code{readline ()} was called, reset the signal handling to what it was +before @code{readline ()} was called, and resend the signal to the calling +application. +If and when the calling application's signal handler returns, Readline +will reinitialize the terminal and continue to accept input. +When a @code{SIGINT} is received, the Readline signal handler performs +some additional work, which will cause any partially-entered line to be +aborted (see the description of @code{rl_free_line_state ()}). + +There is an additional Readline signal handler, for @code{SIGWINCH}, which +the kernel sends to a process whenever the terminal's size changes (for +example, if a user resizes an @code{xterm}). The Readline @code{SIGWINCH} +handler updates Readline's internal screen size state, and then calls any +@code{SIGWINCH} signal handler the calling application has installed. +Readline calls the application's @code{SIGWINCH} signal handler without +resetting the terminal to its original state. If the application's signal +handler does more than update its idea of the terminal size and return (for +example, a @code{longjmp} back to a main processing loop), it @emph{must} +call @code{rl_cleanup_after_signal ()} (described below), to restore the +terminal state. + +Readline provides two variables that allow application writers to +control whether or not it will catch certain signals and act on them +when they are received. It is important that applications change the +values of these variables only when calling @code{readline ()}, not in +a signal handler, so Readline's internal signal state is not corrupted. + +@deftypevar int rl_catch_signals +If this variable is non-zero, Readline will install signal handlers for +@code{SIGINT}, @code{SIGQUIT}, @code{SIGTERM}, @code{SIGALRM}, +@code{SIGTSTP}, @code{SIGTTIN}, and @code{SIGTTOU}. + +The default value of @code{rl_catch_signals} is 1. +@end deftypevar + +@deftypevar int rl_catch_sigwinch +If this variable is non-zero, Readline will install a signal handler for +@code{SIGWINCH}. + +The default value of @code{rl_catch_sigwinch} is 1. +@end deftypevar + +If an application does not wish to have Readline catch any signals, or +to handle signals other than those Readline catches (@code{SIGHUP}, +for example), +Readline provides convenience functions to do the necessary terminal +and internal state cleanup upon receipt of a signal. + +@deftypefun void rl_cleanup_after_signal (void) +This function will reset the state of the terminal to what it was before +@code{readline ()} was called, and remove the Readline signal handlers for +all signals, depending on the values of @code{rl_catch_signals} and +@code{rl_catch_sigwinch}. +@end deftypefun + +@deftypefun void rl_free_line_state (void) +This will free any partial state associated with the current input line +(undo information, any partial history entry, any partially-entered +keyboard macro, and any partially-entered numeric argument).
