extras/net/Makefile:
Build a Mercury.modules as some file names do not match
their module names and the compiler no longer accepts this.
extras/net/errno.m:
Ensure we can see the definition of MR_STRERROR_BUF_SIZE.
Discussion of these changes can be found on the Mercury developers
mailing list archives from June 2018.
COPYING.LIB:
Add a special linking exception to the LGPL.
*:
Update references to COPYING.LIB.
Clean up some minor errors that have accumulated in copyright
messages.
This library had been neglected for a while and came to my attention when it
used deprecated (or at least old) C interfaces rather than newer reentrant
ones. I've started to improve this library by giving a more typesafe and
Mercury-esque API, using only reentrant C functions, and eventually adding
support for more protocols, (eg: IPv6 and UDP) better integration with
Mercury's io module and generally making it easier to use.
What's working now:
+ creating sockets,
+ binding and listening,
+ connecting (untested),
+ accepting,
+ closing.
+ The interface is generally more type-safe, using new types suck as
"socket" and "address" rather than "int" and "c_pointer".
What's not working/incomplete:
+ I havn't yet touched the tcp.m module, but I intend to remove it and
create a new high-level interface for various protocols.
+ Any kind of reading / writing over sockets at all.
+ Name lookups.
+ A lot of the interface is incomplete / missing useful functions and
predicates.
This is a work in progress.
Makefile:
New Makefile.
README.md:
New Readme file.
net.m:
net is now a module containing the other modules as submodules.
sockets.m:
Many changes as described above.
netdb.m:
This new module contains host and other name lookups. Only service
lookups are currently implemented.
types.m:
Types shared by sockets.m and netdb.m.
echo.m:
An example echo server.
errno.m:
strerror functionality.
tcp.m:
Conform to changes in net.m.
