56 | =head1 BEFORE YOU START USING THIS MODULE |
|
|
57 | |
|
|
58 | If you only need timer, I/O, signal, child and idle watchers and not the |
|
|
59 | advanced functionality of this module, consider using L<AnyEvent> instead, |
|
|
60 | specifically the simplified API described in L<AE>. |
|
|
61 | |
|
|
62 | When used with EV as backend, the L<AE> API is as fast as the native L<EV> |
|
|
63 | API, but your programs/modules will still run with many other event loops. |

82 | =head2 PORTING FROM EV 3.X to 4.X |
|
|
83 | |
|
|
84 | EV version 4 introduces a number of incompatible changes summarised |
|
|
85 | here. According to the depreciation strategy used by libev, there is a |
|
|
86 | compatibility layer in place so programs should continue to run unchanged |
|
|
87 | (the XS interface lacks this layer, so programs using that one need to be |
|
|
88 | updated). |
|
|
89 | |
|
|
90 | This compatibility layer will be switched off in some future release. |
|
|
91 | |
|
|
92 | All changes relevant to Perl are renames of symbols, functions and |
|
|
93 | methods: |
|
|
94 | |
|
|
95 | EV::loop => EV::run |
|
|
96 | EV::LOOP_NONBLOCK => EV::RUN_NOWAIT |
|
|
97 | EV::LOOP_ONESHOT => EV::RUN_ONCE |
|
|
98 | |
|
|
99 | EV::unloop => EV::break |
|
|
100 | EV::UNLOOP_CANCEL => EV::BREAK_CANCEL |
|
|
101 | EV::UNLOOP_ONE => EV::BREAK_ONE |
|
|
102 | EV::UNLOOP_ALL => EV::BREAK_ALL |
|
|
103 | |
|
|
104 | EV::TIMEOUT => EV::TIMER |
|
|
105 | |
|
|
106 | EV::loop_count => EV::iteration |
|
|
107 | EV::loop_depth => EV::depth |
|
|
108 | EV::loop_verify => EV::verify |
|
|
109 | |
|
|
110 | The loop object methods corresponding to the functions above have been |
|
|
111 | similarly renamed. |

|
|
249 | |
|
|
250 | Establishes the current time by querying the kernel, updating the time |
|
|
251 | returned by C<EV::now> in the progress. This is a costly operation and |
|
|
252 | is usually done automatically within C<EV::loop>. |
|
|
253 | |
|
|
254 | This function is rarely useful, but when some event callback runs for a |
|
|
255 | very long time without entering the event loop, updating libev's idea of |
|
|
256 | the current time is a good idea. |

|
|
263 | |
|
|
264 | =item $loop->resume |
|
|
265 | |
|
|
266 | These two functions suspend and resume a loop, for use when the loop is |
|
|
267 | not used for a while and timeouts should not be processed. |
|
|
268 | |
|
|
269 | A typical use case would be an interactive program such as a game: When |
|
|
270 | the user presses C<^Z> to suspend the game and resumes it an hour later it |
|
|
271 | would be best to handle timeouts as if no time had actually passed while |
|
|
272 | the program was suspended. This can be achieved by calling C<suspend> |
|
|
273 | in your C<SIGTSTP> handler, sending yourself a C<SIGSTOP> and calling |
|
|
274 | C<resume> directly afterwards to resume timer processing. |
|
|
275 | |
|
|
276 | Effectively, all C<timer> watchers will be delayed by the time spend |
|
|
277 | between C<suspend> and C<resume>, and all C<periodic> watchers |
|
|
278 | will be rescheduled (that is, they will lose any events that would have |
|
|
279 | occured while suspended). |
|
|
280 | |
|
|
281 | After calling C<suspend> you B<must not> call I<any> function on the given |
|
|
282 | loop other than C<resume>, and you B<must not> call C<resume> |
|
|
283 | without a previous call to C<suspend>. |
|
|
284 | |
|
|
285 | Calling C<suspend>/C<resume> has the side effect of updating the event |
|
|
286 | loop time (see C<now_update>). |

|
|
1032 | |
|
|
1033 | Like all other watcher types, there is a bitmask constant for use in |
|
|
1034 | C<$revents> and other places. The C<EV::CHECK> is special as it has |
|
|
1035 | the same name as the C<CHECK> sub called by Perl. This doesn't cause |
|
|
1036 | big issues on newer perls (beginning with 5.8.9), but it means thatthe |
|
|
1037 | constant must be I<inlined>, i.e. runtime calls will not work. That means |
|
|
1038 | that as long as you always C<use EV> and then C<EV::CHECK> you are on the |
|
|
1039 | safe side. |
