zmq_pollitem_t handling will be less than pretty -- which is why documentation needs to be written.
current interface of returning exception feels awkward.
For both API and users guide.
need to finish translations of examples http://zguide.zeromq.org/page:all
Consider the following trivial example:
\l qzmq.q
ctx:zctx.new[]
socket:zsocket.new[ctx; zmq`DEALER]
zsocket.bind[socket; `$"tcp://*:9001"]
zsocket.destroy[ctx; socket]
zctx.destroy[ctx]
\\
This works fine, and you will see the port number printed out to the q console which indicates that the port bound properly. Now notice if you add a semicolon after the bind line:
\l qzmq.q
ctx:zctx.new[]
socket:zsocket.new[ctx; zmq`DEALER]
zsocket.bind[socket; `$"tcp://*:9001"];
zsocket.destroy[ctx; socket]
zctx.destroy[ctx]
\\
Now the bind does not occur. I'm still pretty new to q, but as far as I can tell semicolons shouldn't affect the calls of functions.
BTW this is KDB+ 2.7 2011.03.23 if that helps at all.
Because symbols are interned strings, they don't GCed. Symbols are nice in that there can be no accidental mutation but come at a high cost of memory leak.
e.g. xt==-10h, yt==KC, yt==KG, etc. so that wrong types do not propagate downward to unsuspecting library.
qzmq needs a more sensible build/integration mechanism to cover different platforms/versions of kdb+, ØMQ and CZMQ.
Just curious. Looks like zthread.fork
is also gone. I can't find the rationale in the repo for removing them.
For the 0MQ Guide as examples are going to be included therein.
Either rewrite it or pair with free() as the owner of the pointer.
