Install a public "gnetworking.h" header that can be used to include the relevant OS-dependent networking headers. This does not really abstract away unix-vs-windows however; error codes, in particular, are incompatible. gnetworkingprivate.h now contains just a few internal URI-related functions Also add a g_networking_init() function to gnetworking.h, which can be used to explicitly initialize OS-level networking, rather than having that happen as a side-effect of registering GInetAddress. https://bugzilla.gnome.org/show_bug.cgi?id=623187

|
|
*
|
|
* The <literal>gnetworking.h</literal> header can be included to get
|
|
* various low-level networking-related system headers, automatically
|
|
* taking care of certain portability issues for you.
|
|
*
|
|
* This can be used, for example, if you want to call setsockopt()
|
|
* on a #GSocket.
|
|
*
|
|
* Note that while WinSock has many of the same APIs as the
|
|
* traditional UNIX socket API, most of them behave at least slightly
|
|
* differently (particularly with respect to error handling). If you
|
|
* want your code to work under both UNIX and Windows, you will need
|
|
* to take these differences into account.
|
|
*
|
|
* Also, under glibc, certain non-portable functions are only visible
|
|
* in the headers if you define <literal>_GNU_SOURCE</literal> before
|
|
* including them. Note that this symbol must be defined before
|
|
* including <emphasis>any</emphasis> headers, or it may not take
|
|
* effect.
