1605 | =head3 ABI Issues (Largefile Support) |
|
|
1606 | |
|
|
1607 | Libev by default (unless the user overrides this) uses the default |
|
|
1608 | compilation environment, which means that on systems with optionally |
|
|
1609 | disabled large file support, you get the 32 bit version of the stat |
|
|
1610 | structure. When using the library from programs that change the ABI to |
|
|
1611 | use 64 bit file offsets the programs will fail. In that case you have to |
|
|
1612 | compile libev with the same flags to get binary compatibility. This is |
|
|
1613 | obviously the case with any flags that change the ABI, but the problem is |
|
|
1614 | most noticably with ev_stat and largefile support. |

2525 | =head1 OTHER LANGUAGE BINDINGS |
|
|
2526 | |
|
|
2527 | Libev does not offer other language bindings itself, but bindings for a |
|
|
2528 | numbe rof languages exist in the form of third-party packages. If you know |
|
|
2529 | any interesting language binding in addition to the ones listed here, drop |
|
|
2530 | me a note. |

2536 | The EV module implements the full libev API and is actually used to test |
|
|
2537 | libev. EV is developed together with libev. Apart from the EV core module, |
|
|
2538 | there are additional modules that implement libev-compatible interfaces |
|
|
2539 | to C<libadns> (C<EV::ADNS>), C<Net::SNMP> (C<Net::SNMP::EV>) and the |
|
|
2540 | C<libglib> event core (C<Glib::EV> and C<EV::Glib>). |
