recv

See the current Perl documentation for recv.

Here is our local, out-dated (pre-5.6) version:


recv - receive a message over a Socket



recv SOCKET,SCALAR,LEN,FLAGS



Receives a message on a socket. Attempts to receive LENGTH bytes of data into variable SCALAR from the specified SOCKET filehandle. Actually does a C recvfrom(), so that it can return the address of the sender. Returns the undefined value if there's an error. SCALAR will be grown or shrunk to the length actually read. Takes the same flags as the system call of the same name. See UDP: Message Passing for examples.

[stevieb]: heh, yeah, sorry. This is integration testing for certain. In fact, it's even Continuous Integration ;)
[stevieb]: Obviously, Travis CI just won't cut it for these distributions...
[stevieb]: I went on my merry way writing a cross-platform, network-aware system that works across Perlbrew and Berrybrew systems and runs unit tests for Perl dists on all installed versions, with the ability to manage *brew commands themselves
[stevieb]: That worked out exceptionally well, as when I started that project, I hadn't delved into hardware development yet.
[stevieb]: found a issue in MetaCPAN::Client though today for my revdep tests. At least I think it's an issue
