-+.SH DESCRIPTION
- The
--.Nm event
-+\fIevent\fP\fR
- API provides a mechanism to execute a function when a specific event
- on a file descriptor occurs or after a given time has passed.
--.Pp
-+.PP
- The
--.Nm event
-+\fIevent\fP\fR
- API needs to be initialized with
--.Fn event_init
-+\fBevent_init\fR
- before it can be used.
--.Pp
-+.PP
- In order to process events, an application needs to call
--.Fn event_dispatch .
-+\fBevent_dispatch\fP\fR.
- This function only returns on error, and should replace the event core
- of the application program.
--.Pp
-+.PP
- The function
--.Fn event_set
-+\fBevent_set\fP\fR
- prepares the event structure
--.Fa ev
-+\fIev\fP\fR
- to be used in future calls to
--.Fn event_add
-+\fBevent_add\fP\fR
- and
--.Fn event_del .
-+\fBevent_del\fP\fR .
- The event will be prepared to call the function specified by the
--.Fa fn
-+\fIfn\fP\fR
- argument with an
--.Fa int
-+\fIint\fP\fR
- argument indicating the file descriptor, a
--.Fa short
-+\fIshort\fP\fR
- argument indicating the type of event, and a
--.Fa void *
-+\fIvoid*\fP\fR
- argument given in the
--.Fa arg
-+\fIarg\fP\fR
- argument.
- The
--.Fa fd
-+The \fIfd\fP\fR
- indicates the file descriptor that should be monitored for events.
--The events can be either
--.Va EV_READ ,
--.Va EV_WRITE ,
--or both,
-+The events can be either EV_READ, EV_WRITE , or both,
- indicating that an application can read or write from the file descriptor
- respectively without blocking.
--.Pp
-+.PP
- The function
--.Fa fn
-+\fIfn\fP\fR
- will be called with the file descriptor that triggered the event and
- the type of event which will be either
--.Va EV_TIMEOUT ,
--.Va EV_SIGNAL ,
--.Va EV_READ ,
-+EV_TIMEOUT,
-+EV_SIGNAL,
-+EV_READ,
- or
--.Va EV_WRITE .
-+EV_WRITE.
- Additionally, an event which has registered interest in more than one of the
- preceeding events, via bitwise-OR to
--.Fn event_set ,
-+\fBevent_set\fP\fR,
- can provide its callback function with a bitwise-OR of more than one triggered
- event.
- The additional flag
--.Va EV_PERSIST
-+EV_PERSIST
- makes an
--.Fn event_add
-+\fBevent_add\fP\fR
- persistent until
--.Fn event_del
-+\fBevent_del\fP\fR
- has been called.
--.Pp
-+.PP
- Once initialized, the
--.Fa ev
-+\fIev\fP\fR
- structure can be used repeatedly with
--.Fn event_add
-+\fBevent_add\fP\fR
- and
--.Fn event_del
-+\fBevent_del\fP\fR
- and does not need to be reinitialized unless the function called and/or
- the argument to it are to be changed.
- However, when an
--.Fa ev
-+\fIev\fP\fR
- structure has been added to libevent using
--.Fn event_add
-+\fBevent_add\fP\fR
- the structure must persist until the event occurs (assuming
--.Fa EV_PERSIST
-+EV_PERSIST
- is not set) or is removed
- using
--.Fn event_del .
-+\fBevent_del\fP\fR.
- You may not reuse the same
--.Fa ev
-+\fIev\fP\fR
- structure for multiple monitored descriptors; each descriptor
- needs its own
--.Fa ev .
--.Pp
-+\fIev\fP\fR.
-+.PP
- The function
--.Fn event_add
-+\fBevent_add\fP\fR
- schedules the execution of the
--.Fa ev
-+\fIev\fP\fR
- event when the event specified in
--.Fn event_set
-+\fBevent_set\fP\fR
- occurs or in at least the time specified in the
--.Fa tv .
-+\fItv\fP\fR
- If
--.Fa tv
-+\fItv\fP\fR
- is
--.Dv NULL ,
-+\fINULL\fP\fR,
- no timeout occurs and the function will only be called
- if a matching event occurs on the file descriptor.
- The event in the
--.Fa ev
-+\fIev\fP\fR
- argument must be already initialized by
--.Fn event_set
-+\fBevent_set\fP\fR
- and may not be used in calls to
--.Fn event_set
-+\fBevent_set\fP\fR
- until it has timed out or been removed with
--.Fn event_del .
-+\fBevent_del\fP\fR.
- If the event in the
--.Fa ev
-+\fIev\fP\fR
- argument already has a scheduled timeout, the old timeout will be
- replaced by the new one.
--.Pp
-+.PP
- The function
--.Fn event_del
-+\fBevent_del\fP\fR
- will cancel the event in the argument
--.Fa ev .
-+\fIev\fP\fR.
- If the event has already executed or has never been added
- the call will have no effect.
--.Pp
-+.PP
- The functions
--.Fn evtimer_set ,
--.Fn evtimer_add ,
--.Fn evtimer_del ,
--.Fn evtimer_initialized ,
-+\fBevtimer_set\fP\fR,
-+\fBevtimer_add\fP\fR,
-+\fBevtimer_del\fP\fR,
-+\fBevtimer_initialized\fP\fR,
- and
--.Fn evtimer_pending
-+\fBevtimer_pending\fP\fR
- are abbreviations for common situations where only a timeout is required.
- The file descriptor passed will be \-1, and the event type will be
--.Va EV_TIMEOUT .
--.Pp
-+EV_TIMEOUT.
-+.PP
- The functions
--.Fn signal_set ,
--.Fn signal_add ,
--.Fn signal_del ,
--.Fn signal_initialized ,
-+\fBsignal_set\fP\fR,
-+\fBsignal_add\fP\fR,
-+\fBsignal_del\fP\fR,
-+\fBsignal_initialized\fP\fR,
- and
--.Fn signal_pending
-+\fBsignal_pending\fP\fR
- are abbreviations.
- The event type will be a persistent
--.Va EV_SIGNAL .
-+EV_SIGNAL .
- That means
--.Fn signal_set
-+\fBsignal_set\fP\fR
- adds
--.Va EV_PERSIST .
--.Pp
-+EV_PERSIST.
-+.PP
- In order to avoid races in signal handlers, the
--.Nm event
-+\fIevent\fP\fR
- API provides two variables:
--.Va event_sigcb
-+\fBevent_sigcb\fP\fR
- and
--.Va event_gotsig .
-+\fBevent_gotsig\fP\fR.
- A signal handler
- sets
--.Va event_gotsig
-+\fBevent_gotsig\fP\fR
- to indicate that a signal has been received.
- The application sets
--.Va event_sigcb
-+\fBevent_sigcb\fP\fR
- to a callback function.
- After the signal handler sets
--.Va event_gotsig ,
--.Nm event_dispatch
-+\fBevent_gotsig\fP\fR,
-+\fBevent_dispatch()\fP\fR
