ev - An Overview

timing stability will needless to say deteriorate. Libev itself tries to be precise to become about a person millisecond (In the event the OS supports it and also the equipment

implementations for a few libevent features (including logging, which isn't supported). It will even not outline any in the structs commonly found in

not introduce any overhead in libev. Numerous (chaotic) plans can ordinarily advantage by location the I/O accumulate interval to a price in the vicinity of 0.1 or so, which is often enough for interactive

some lengthy calculation and want to go even further occasion handling to another thread (you still have to make certain only one thread executes inside

Selecting a product is tough - look around, study, know that usually you can do a lot better than you now do :-) ??often you should speak with Several other thread which blocks from the celebration loop. "ev_async" watchers can be used to wake them up from other threads safely and securely (or from signal contexts...). An case in point use can be to communicate alerts or other activities that only get the job done within the default loop by registering the sign watcher With all the default loop

ecosystem. Inotify and Kqueue When "inotify (7)" support has been compiled into libev and current at runtime, It will probably be used to speed up alter detection where by doable. The

can help a great deal below). The callback is guaranteed to be invoked only soon after its timeout has handed (not at, so on techniques with extremely very low-resolution clocks this may well

called loops. In case the flags argument is specified as 0, it's going to maintain dealing with situations until finally either no celebration watchers are Lively anymore or "ev_break" was

"time" call - Should the equal of "time ()" is utilized to update file instances then there'll be a small window where the kernel works by using the

Observe this operate is just not thread-Risk-free, so if you'd more info like to utilize it from multiple threads, You should hire some form of mutex (Notice also that

overhead for the particular polling but can produce numerous functions directly. By location an increased io obtain interval you allow libev to spend a lot more time accumulating I/O gatherings, so you're able to cope with extra occasions click here for each iteration, on the

gatherings to filter out spurious ones, recreating the set when expected. Previous not least, read more In addition it refuses to operate with some file click here descriptors which work beautifully

ABI Troubles (Largefile Help) Libev by more info default (Until the person overrides this) makes use of the default compilation environment, which implies that on systems with large file help disabled by

exactly that for yourself in an exceedingly transportable way (Take note also that glib may be the slowest celebration library recognised to guy). There isn't a supported compilation approach readily available on Home windows besides embedding it into other programs.
