Deprecated List

Global evbuffer_readline

This function is deprecated because its behavior is not correct for almost any protocol, and also because it's wholly subsumed by evbuffer_readln().

Global evbuffer_setcb

This function is deprecated because it clears all previous callbacks set on the evbuffer, which can cause confusing behavior if multiple parts of the code all want to add their own callbacks on a buffer. Instead, use evbuffer_add(), evbuffer_del(), and evbuffer_setflags() to manage your own evbuffer callbacks without interfering with callbacks set by others.

Global evdns_add_server_port

This function is deprecated because it does not allow the caller to specify which even_base it uses. The recommended function is evdns_add_server_port_with_base().

Global evdns_clear_nameservers_and_suspend

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_clear_nameservers_and_suspend().

Global evdns_count_nameservers

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_count_nameservers().

Global evdns_get_global_base
This function is deprecated because use of the global evdns_base is error-prone.

Global evdns_init

This function is deprecated because it always uses the current event base, and is easily confused by multiple calls to event_init(), and so is not safe for multithreaded use. Additionally, it allocates a global structure that only one thread can use. The replacement is evdns_base_new().

Global evdns_nameserver_add

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_nameserver_add().

Global evdns_nameserver_ip_add

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_nameserver_ip_add().

Global evdns_resolv_conf_parse

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_resolv_conf_parse().

Global evdns_resolve_ipv4

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_resolve_ipv4().

Global evdns_resolve_reverse

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_resolve_reverse().

Global evdns_resolve_reverse_ipv6

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_resolve_reverse_ipv6().

Global evdns_resume

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_resume().

Global evdns_search_add

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_search_add().

Global evdns_search_clear
This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_search_clear().

Global evdns_search_ndots_set

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_search_ndots_set().

Global evdns_set_option

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_set_option().

Global evdns_shutdown

This function is deprecated because it does not allow the caller to specify which evdns_base it applies to. The recommended function is evdns_base_shutdown().

File event_compat.h
All functions in this file are by definition deprecated.

Global event_dispatch

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().

Global event_get_method

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().

Global event_init

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

Global event_loop

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().

Global event_loopbreak

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().

Global event_loopexit

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().

Global event_once

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().

Global event_priority_init

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().

Global event_set
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.

Global evhttp_connection_new
It does not allow an event base to be specified

Global evhttp_connection_set_base
XXXX Why?

Global evhttp_decode_uri

This function is deprecated; you probably want to use evhttp_get_decoded_uri instead.

Global evhttp_parse_query

This function is deprecated as of Libevent 2.0.9. Use evhttp_uri_parse and evhttp_parse_query_str instead.

Global evhttp_start

It does not allow an event base to be specified

Group Misnamed functions

These macros are deprecated because their names don't follow Libevent's naming conventions. Use evtag_encode_int and evtag_encode_int64 instead.

Group signal_* macros

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

Group timeout_* macros

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