NAME
       event_compat -

       Potentially non-threadsafe versions of the functions in event.h:
       provided only for backwards compatibility.


SYNOPSIS
       #include <event2/event_compat.h>
       #include <event2/event-config.h>
       #include <event2/util.h>

       Deprecated
           These macros are deprecated because their naming is inconsistent
           with the rest of Libevent. Use the evtimer_* macros instead.

Detailed Description
       Potentially non-threadsafe versions of the functions in event.h:
       provided only for backwards compatibility.

       In the oldest versions of Libevent, event_base was not a first-class
       structure. Instead, there was a single event base that every function
       manipulated. Later, when separate event bases were added, the old
       functions that didn't take an event_base argument needed to work by
       manipulating the 'current' event base. This could lead to thread-safety
       issues, and obscure, hard-to-diagnose bugs.

       Deprecated
           All functions in this file are by definition deprecated.


Function Documentation
   int event_dispatch (void)
       Loop to process events. Like event_base_dispatch(), but uses the
       'current' base.

       Deprecated
           This function is deprecated because it is easily confused by
           multiple calls to event_init(), and because it is not safe for
           multithreaded use. The replacement is event_base_dispatch().

       See Also:
           event_base_dispatch(), event_init()


   const char* event_get_method (void)
       Get the kernel event notification mechanism used by Libevent.
       Deprecated
           This function is obsolete, and has been replaced by
           event_base_get_method(). Its use is deprecated because it relies on
           the 'current' base configured by event_init().

       See Also:
           event_base_get_method()


   struct event_base* event_init (void) [read]
       Initialize the event API. The event API needs to be initialized with
       event_init() before it can be used. Sets the global current base that
       gets used for events that have no base associated with them.

       Deprecated
           This function is deprecated because it replaces the 'current'
           event_base, and is totally unsafe for multithreaded use. The
           replacement is event_base_new().

       See Also:
           event_base_set(), event_base_new()


   int event_loop (int)
       Handle events. This function behaves like event_base_loop(), but uses
       the 'current' base

       Deprecated
           This function is deprecated because it uses the event base from the
           last call to event_init, and is therefore not safe for
           multithreaded use. The replacement is event_base_loop().

       See Also:
           event_base_loop(), event_init()


   int event_loopbreak (void)
       Abort the active event_loop() immediately. This function behaves like
       event_base_loopbreakt(), except that it uses the 'current' base.

       Deprecated
           This function is deprecated because it uses the event base from the
           last call to event_init, and is therefore not safe for
           multithreaded use. The replacement is event_base_loopbreak().

       See Also:
           event_base_loopbreak(), event_init()


   int event_loopexit (const struct timeval *)
       Exit the event loop after the specified time. This function behaves
       like event_base_loopexit(), except that it uses the 'current' base.

       Deprecated
           This function is deprecated because it uses the event base from the
           last call to event_init, and is therefore not safe for
           multithreaded use. The replacement is event_base_loopexit().

       See Also:
           event_init, event_base_loopexit()


   int event_once (evutil_socket_t, short, void(*)(evutil_socket_t, short,
   void *), void *, const struct timeval *)
       Schedule a one-time event to occur. Deprecated
           This function is obsolete, and has been replaced by
           event_base_once(). Its use is deprecated because it relies on the
           'current' base configured by event_init().

       See Also:
           event_base_once()


   int event_priority_init (int)
       Set the number of different event priorities. Deprecated
           This function is deprecated because it is easily confused by
           multiple calls to event_init(), and because it is not safe for
           multithreaded use. The replacement is event_base_priority_init().

       See Also:
           event_base_priority_init()


   void event_set (struct event *, evutil_socket_t, short,
   void(*)(evutil_socket_t, short, void *), void *)
       Prepare an event structure to be added. Deprecated
           event_set() is not recommended for new code, because it requires a
           subsequent call to event_base_set() to be safe under most
           circumstances. Use event_assign() or event_new() instead.
