# gnetworking.h
|
||
|
|
|
||
|
|
The `<gio/gnetworking.h>` 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()`](man:setsockopt(2)) on a [class@Gio.Socket].
|
||
|
|
|
||
|
|
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 GNU libc, certain non-portable functions are only visible
|
||
|
|
in the headers if you define `_GNU_SOURCE` before including them. Note
|
||
|
|
that this symbol must be defined before including any headers, or it
|
||
|
|
may not take effect.
|
||
|
|
|
||
|
|
There is one function provided specifically for initialising the networking
|
||
|
|
APIs, which needs to be called only if they are being used before GLib
|
||
|
|
initialises itself:
|
||
|
|
|
