<p>
The GnomeVFSSocket function family unifies network I/O through functions
similar to the standard POSIX read/write functions. The main difference is
that all operations are cancellable through the standard GnomeVFS cancellation
mechanism and you can specify a maximum amount of time an operation may take
through <a class="link" href="gnome-vfs-2.0-gnome-vfs-socket.html#gnome-vfs-socket-set-timeout" title="gnome_vfs_socket_set_timeout ()"><span class="type">gnome_vfs_socket_set_timeout</span></a>.
