|
||
|
|
*
|
||
|
|
* 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.
