Abstract
This chapter covers network programming with Vala. We’re introducing the low-level way using POSIX sockets first and then advance to using GIO. Since most web services these days are talking JSON, we’re also going to introducing this. Last but not least, we will present the GNOME HTTP networking library libsoup.

Notes
- 1.
In fact they support much more, e.g., SCTP, DCCP, IPPROTO_RAW, ICMP. TCP and UDP are the most common ones though.
- 2.
Of course, we could have used something like libntp to handle all the nitty and gritty low-level details, but that would be “cheating.”
- 3.
Functions defined in POSIX often return pointers to internal storage, which are not supposed to be released by the caller. In Vala, these functions are mapped as methods returning unowned types.
