Bindings and high level interface for to ENet v1.3.9
|Latest on Hackage:||126.96.36.199|
This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
ENet is a networking library on top of UDP. In it's own words:
"ENet's purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP (User Datagram Protocol). The primary feature it provides is optional reliable, in-order delivery of packets.
ENet omits certain higher level networking features such as authentication, lobbying, server discovery, encryption, or other similar tasks that are particularly application specific so that the library remains flexible, portable, and easily embeddable."
This library contains both bindings and a slightly cleaned up interface on
top. The bindings are as close to the original as possible. Names are striped
of the leading
enet_ and converted to CamelCase, and the occasional newtype
is used instead, but otherwise all functions signatures are exactly the
same. The bindings are in
The higher level interface is all other exposed modules. Functions like
enet_host_* are placed in
Network.ENet.Host. All functions are present
except for the
enet_socket* functions: they are just wrappers of the Posix
Sockets Interface, which is already provided in Haskell by the
package. Changes are fairly minimal:
Out-Args are now returned with a tuple,
conversions between C and Haskell types happen automatically (when Haskell
versions exists), and nullable pointer types have been replaced with
Maybes. In short, there should be very few reasons to use the raw bindings
over the "nice" interface.
At the moment, consult the ENet website for documentation. In the vast majority of cases the documentation there should apply here exactly, I will try to add Haddock documentation for everywhere it does not.
ENet currently only supports IPv4 at the moment (though that should soon
change), and must be called from only one bound thread (i.e. thread created
forkOS). Richer native networking libraries leveraging Haskell's
strengths exist, and for new projects I'd recommend those. But for interfacing
with existing protocols using ENet, this package should be quite useful.
