+.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 .
+\fIevent_dispatch\fP\fR .
 This function only returns on error, and should replace the event core
 of the application program.
-.Pp
+.PP
 In order to avoid races in signal handlers, the
-.Nm event
+\fIevent\fP\fR
 API provides two variables:
-.Va event_sigcb
+\fIevent_sigcb\fP\fR
 and
-.Va event_gotsig .
+\fIevent_gotsig\fP\fR.
 A signal handler
 sets
-.Va event_gotsig
+\fIevent_gotsig\fP\fR
 to indicate that a signal has been received.
 The application sets
-.Va event_sigcb
+\fIevent_sigcb\fP\fR
 to a callback function.
 After the signal handler sets
-.Va event_gotsig ,
-.Nm event_dispatch
+\fIevent_gotsig\fP\fR,
+\fBevent_dispatch()\fP\fR
 will execute the callback function to process received signals.
 The callback returns 1 when no events are registered any more.
 It can return \-1 to indicate an error to the
-.Nm event
+\fIevent\fP\fR
 library, causing
-.Fn event_dispatch
+\fBevent_dispatch\fP\fR
 to terminate with
-.Va errno
-set to
-.Er EINTR .
-.Pp
+\fIerrno\fP\fR
+set to EINTR.
+.PO
 The
-.Nm event_loop
+\fIevent_loop\fP\fR
 function provides an interface for single pass execution of pending
 events.
 The flags
-.Va EVLOOP_ONCE
-and
-.Va EVLOOP_NONBLOCK
-are recognized.
+EVLOOP_ONCE and EVLOOP_NONBLOCK are recognized.
 The
-.Nm event_loopexit
+\fIevent_loopexit\fP\fR
 function allows the loop to be terminated after some amount of time
 has passed.
 The parameter indicates the time after which the loop should terminate.
-.Pp
+.PP
 It is the responsibility of the caller to provide these functions with
 pre-allocated event structures.
-.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 ,
-or
-.Va EV_WRITE .
-The additional flag
-.Va EV_PERSIST
-makes an
-.Fn event_add
-persistent until
-.Fn event_del
+the type of event which will be either EV_TIMEOUT, EV_SIGNAL,
+EV_READ, or EV_WRITE.  The additional flag EV_PERSIST makes an
+\fIevent_add\fP\fR persistent until
+\fIevent_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
+\fIevent_add\fP\fR
 and
-.Fn event_del
+\fIevent_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
+\fIevent_add\fP\fR
 the structure must persist until the event occurs (assuming
-.Fa EV_PERSIST
-is not set) or is removed
-using
-.Fn event_del .
+EV_PERSIST is not set) or is removed using
+\fIevent_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
+needs its own \fIev\fP\fR .
+.PP
 The function
-.Fn event_add
+\fIevent_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
-is
-.Dv NULL ,
-no timeout occurs and the function will only be called
+\fItv\fP\fR
+is NULL, 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
+\fIevent_set\fP\fR
 and may not be used in calls to
-.Fn event_set
+\fIevent_set\fP\fR
 until it has timed out or been removed with
-.Fn event_del .
+\fIevent_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
+\fIevent_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 function
-.Fn event_once
+\fIevent_once\fP\fR
 is similar to
-.Fn event_set .
+\fIevent_set\fP\fR.
 However, it schedules a callback to be called exactly once and does not
 require the caller to prepare an
-.Fa event
+\fIevent\fP\fR
 structure.
-This function supports
-.Fa EV_TIMEOUT ,
-.Fa EV_READ ,
-and
-.Fa EV_WRITE .
-.Pp
+This function supports EV_TIMEOUT, EV_READ, and EV_WRITE.
+.PP
 The
-.Fn event_pending
+\fIevent_pending\fP\fR
 function can be used to check if the event specified by
-.Fa event
+\fIevent\fP\fR
 is pending to run.
-If
-.Va EV_TIMEOUT
-was specified and
-.Fa tv
-is not
-.Dv NULL ,
+If EV_TIMEOUT was specified and
+\fItv\fP\fR
+is not NULL ,
 the expiration time of the event will be returned in
-.Fa tv .
-.Pp
+\fItv\fP\fR .
+.PP
 The
-.Fn event_initialized
+\fIevent_initialized\fP\fR
 macro can be used to check if an event has been initialized.
-.Pp
+.PP
 The functions
-.Fn evtimer_set ,
-.Fn evtimer_add ,
-.Fn evtimer_del ,
-.Fn evtimer_initialized ,
+\fIevtimer_set()\fP\fR,
+\fIevtimer_add()\fP\fR,
+\fIevtimer_del()\fP\fR,
+\fIevtimer_initialized()\fP\fR,
 and
-.Fn evtimer_pending
+\fIevtimer_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 ,
+\fIsignal_set()\fP\fR,
+\fIsignal_add()\fP]\fR,
+\fIsignal_del()\fP\fR ,
+\fIsignal_initialized()\fP\fR,
 and
-.Fn signal_pending
+\fIsignal_pending()\fP\fR
 are abbreviations.
-The event type will be a persistent
-.Va EV_SIGNAL .
+The event type will be a persistent EV_SIGNAL .
 That means
-.Fn signal_set
-adds
-.Va EV_PERSIST .
-.Pp
+\fIsignal_set\fP\fR adds EV_PERSIST .
+.PP
 It is possible to disable support for
-.Va epoll , kqueue , devpoll , poll
-or
-.Va select
+epoll, kqueue, devpoll, event ports, poll or select
 by setting the environment variable
-.Va EVENT_NOEPOLL , EVENT_NOKQUEUE , EVENT_NODEVPOLL , EVENT_NOPOLL
-or
-.Va EVENT_NOSELECT ,
-respectively.
+EVENT_NOEPOLL, EVENT_NOKQUEUE, EVENT_NODEVPOLL, EVENT_NOEVPORT,
+EVENT_NOPOLL or EVENT_NOSELECT, respectively.
 By setting the environment variable
-.Va EVENT_SHOW_METHOD ,
-.Nm libevent
+EVENT_SHOW_METHOD,
+\fIlibevent\fP\fR
 displays the kernel notification method that it uses.
-.Sh EVENT PRIORITIES
+.SH EVENT PRIORITIES
 By default
-.Nm libevent
+\fIlibevent\fP\fR
 schedules all active events with the same priority.
 However, sometimes it is desirable to process some events with a higher
 priority than others.
 For that reason,
-.Nm libevent
+\fIlibevent\fP\fR
 supports strict priority queues.
 Active events with a lower priority are always processed before events
 with a higher priority.
-.Pp
+.PP
 The number of different priorities can be set initially with the
-.Fn event_priority_init
+\fIevent_priority_init()\fP\fR
 function.
 This function should be called before the first call to
-.Fn event_dispatch .
+\fIevent_dispatch()\fP\fR .
 The
-.Fn event_priority_set
+\fIevent_priority_set()\fP\fR
 function can be used to assign a priority to an event.
 By default,
-.Nm libevent
+\fIlibevent\fP\fR
 assigns the middle priority to all events unless their priority
 is explicitly set.
-.Sh THREAD SAFE EVENTS
-.Nm Libevent
+.SH THREAD SAFE EVENTS
+\fIlibevent\fP\fR
 has experimental support for thread-safe events.
 When initializing the library via
-.Fn event_init ,
+\fIevent_init()\fP\fR,
 an event base is returned.
 This event base can be used in conjunction with calls to
-.Fn event_base_set ,
-.Fn event_base_dispatch ,
-.Fn event_base_loop ,
-.Fn event_base_loopexit ,
-.Fn bufferevent_base_set
+\fIevent_base_set()\fP\fR,
+\fIevent_base_dispatch()\fP\fR,
+\fIevent_base_loop()\fP\fR,
+\fIevent_base_loopexit()\fP\fR,
+\fIbufferevent_base_set()\fP\fR
 and
-.Fn event_base_free .
-.Fn event_base_set
+\fIevent_base_free()\fP\fR.
+\fIevent_base_set()\fP\fR 
 should be called after preparing an event with
-.Fn event_set ,
+\fIevent_set()\fP\fR,
 as
-.Fn event_set
+\fIevent_set()\fP\fR
 assigns the provided event to the most recently created event base.
-.Fn bufferevent_base_set
+\fIbufferevent_base_set()\fP\fR
 should be called after preparing a bufferevent with
-.Fn bufferevent_new .
-.Fn event_base_free
+\fIbufferevent_new()\fP\fR.
+\fIevent_base_free()\fP\fR
 should be used to free memory associated with the event base
 when it is no longer needed.
-.Sh BUFFERED EVENTS
-.Nm libevent
+.SH BUFFERED EVENTS
+\fIlibevent\fP\fR
 provides an abstraction on top of the regular event callbacks.
 This abstraction is called a
-.Va "buffered event" .
+\fB"buffered event"\fP\fR.
 A buffered event provides input and output buffers that get filled
 and drained automatically.
 The user of a buffered event no longer deals directly with the IO,
 but instead is reading from input and writing to output buffers.
-.Pp
+.PP
 A new bufferevent is created by
-.Fn bufferevent_new .
+\fIbufferevent_new()\fP\fR.
 The parameter
-.Fa fd
+\fIfd\fP\fR
 specifies the file descriptor from which data is read and written to.
 This file descriptor is not allowed to be a
-.Xr pipe 2 .
+\fBpipe(2)\fR.
 The next three parameters are callbacks.
 The read and write callback have the following form:
-.Ft void
-.Fn "(*cb)" "struct bufferevent *bufev" "void *arg" .
+\fBvoid \fB(*cb)\fR\fR(\fBstruct bufferevent* \fIbufev\fP\fR, \fBvoid* \fIarg\fP\fR).
 The error callback has the following form:
-.Ft void
-.Fn "(*cb)" "struct bufferevent *bufev" "short what" "void *arg" .
+\fBvoid \fB(*cb)\fR\fR(\fBstruct bufferevent* \fIbufev\fP\fR, \fBshort \fIwhat\fP\fR, \fBvoid* \fIarg\fP\fR).
 The argument is specified by the fourth parameter
-.Fa "cbarg" .
+\fIcbarg\fP\fR.
 A
-.Fa bufferevent struct
+\fIbufferevent\fP\fR struct
 pointer is returned on success, NULL on error.
 Both the read and the write callback may be NULL.
 The error callback has to be always provided.
-.Pp
+.PP
 Once initialized, the bufferevent structure can be used repeatedly with
-bufferevent_enable() and bufferevent_disable().
-The flags parameter can be a combination of
-.Va EV_READ
-and
-.Va EV_WRITE .
+\fIbufferevent_enable()\fP\fR and \fIbufferevent_disable()\fP\fR.
+The \fIflags\fP\fR parameter can be a combination of
+EV_READ and EV_WRITE .
 When read enabled the bufferevent will try to read from the file
 descriptor and call the read callback.
 The write callback is executed
 whenever the output buffer is drained below the write low watermark,
-which is
-.Va 0
-by default.
-.Pp
+which is 0 by default.
+.PP
 The
-.Fn bufferevent_write
+\fIbufferevent_write()\fP\fR
 function can be used to write data to the file descriptor.
 The data is appended to the output buffer and written to the descriptor
 automatically as it becomes available for writing.
-.Fn bufferevent_write
+\fIbufferevent_write()\fP\fR
 returns 0 on success or \-1 on failure.
 The
-.Fn bufferevent_read
+\fIbufferevent_read()\fP\fR
 function is used to read data from the input buffer,
 returning the amount of data read.
-.Pp
+.PP
 If multiple bases are in use, bufferevent_base_set() must be called before
 enabling the bufferevent for the first time.
-.Sh NON-BLOCKING HTTP SUPPORT
-.Nm libevent
-provides a very thin HTTP layer that can be used both to host an HTTP
-server and also to make HTTP requests.
-An HTTP server can be created by calling
-.Fn evhttp_start .
-When the HTTP server is no longer used, it can be freed via
-.Fn evhttp_free .
-.Pp
-To be notified of HTTP requests, a user needs to register callbacks with the
-HTTP server.
-This can be done by calling
-.Fn evhttp_set_cb .
-The second argument is the URI for which a callback is being registered.
-The corresponding callback will receive an
-.Va struct evhttp_request
-object that contains all information about the request.
-.Pp
-This section does not document all the possible function calls; please
-check
-.Va event.h
-for the public interfaces.
-.Sh RETURN VALUES
+.SH RETURN VALUES
 Upon successful completion
-.Fn event_add
+\fIevent_add()\fP\fR
 and
-.Fn event_del
+\fIevent_del()\fP\fR
 return 0.
 Otherwise, \-1 is returned and the global variable errno is
 set to indicate the error.
