soup_socket_new ()

SoupSocket *
soup_socket_new (const char *optname1,
                 ...);

Creates a new (disconnected) socket

SoupSocketCallback ()

void
(*SoupSocketCallback) (SoupSocket *sock,
                       guint status,
                       gpointer user_data);

The callback function passed to soup_socket_connect_async().

soup_socket_connect_async ()

void
soup_socket_connect_async (SoupSocket *sock,
                           GCancellable *cancellable,
                           SoupSocketCallback callback,
                           gpointer user_data);

Begins asynchronously connecting to sock 's remote address. The socket will call callback when it succeeds or fails (but not before returning from this function).

If cancellable is non-NULL, it can be used to cancel the connection. callback will still be invoked in this case, with a status of SOUP_STATUS_CANCELLED.

soup_socket_connect_sync ()

guint
soup_socket_connect_sync (SoupSocket *sock,
                          GCancellable *cancellable);

Attempt to synchronously connect sock to its remote address.

If cancellable is non-NULL, it can be used to cancel the connection, in which case soup_socket_connect_sync() will return SOUP_STATUS_CANCELLED.

soup_socket_listen ()

gboolean
soup_socket_listen (SoupSocket *sock);

Makes sock start listening on its local address. When connections come in, sock will emit “new_connection”.

soup_socket_start_ssl ()

gboolean
soup_socket_start_ssl (SoupSocket *sock,
                       GCancellable *cancellable);

Starts using SSL on socket .

soup_socket_start_proxy_ssl ()

gboolean
soup_socket_start_proxy_ssl (SoupSocket *sock,
                             const char *ssl_host,
                             GCancellable *cancellable);

Starts using SSL on socket , expecting to find a host named ssl_host .

soup_socket_is_ssl ()

gboolean
soup_socket_is_ssl (SoupSocket *sock);

Tests if sock is doing (or has attempted to do) SSL.

soup_socket_disconnect ()

void
soup_socket_disconnect (SoupSocket *sock);

Disconnects sock . Any further read or write attempts on it will fail.

soup_socket_is_connected ()

gboolean
soup_socket_is_connected (SoupSocket *sock);

Tests if sock is connected to another host

soup_socket_get_local_address ()

SoupAddress *
soup_socket_get_local_address (SoupSocket *sock);

Returns the SoupAddress corresponding to the local end of sock .

Calling this method on an unconnected socket is considered to be an error, and produces undefined results.

soup_socket_get_remote_address ()

SoupAddress *
soup_socket_get_remote_address (SoupSocket *sock);

Returns the SoupAddress corresponding to the remote end of sock .

Calling this method on an unconnected socket is considered to be an error, and produces undefined results.

soup_socket_get_fd ()

int
soup_socket_get_fd (SoupSocket *sock);

Gets sock 's underlying file descriptor.

Note that fiddling with the file descriptor may break the SoupSocket.

soup_socket_read ()

SoupSocketIOStatus
soup_socket_read (SoupSocket *sock,
                  gpointer buffer,
                  gsize len,
                  gsize *nread,
                  GCancellable *cancellable,
                  GError **error);

Attempts to read up to len bytes from sock into buffer . If some data is successfully read, soup_socket_read() will return SOUP_SOCKET_OK, and *nread will contain the number of bytes actually read (which may be less than len ).

If sock is non-blocking, and no data is available, the return value will be SOUP_SOCKET_WOULD_BLOCK. In this case, the caller can connect to the “readable” signal to know when there is more data to read. (NB: You MUST read all available data off the socket first. “readable” is only emitted after soup_socket_read() returns SOUP_SOCKET_WOULD_BLOCK, and it is only emitted once. See the documentation for “non-blocking”.)

soup_socket_read_until ()

SoupSocketIOStatus
soup_socket_read_until (SoupSocket *sock,
                        gpointer buffer,
                        gsize len,
                        gconstpointer boundary,
                        gsize boundary_len,
                        gsize *nread,
                        gboolean *got_boundary,
                        GCancellable *cancellable,
                        GError **error);

Like soup_socket_read(), but reads no further than the first occurrence of boundary . (If the boundary is found, it will be included in the returned data, and *got_boundary will be set to TRUE.) Any data after the boundary will returned in future reads.

soup_socket_read_until() will almost always return fewer than len bytes: if the boundary is found, then it will only return the bytes up until the end of the boundary, and if the boundary is not found, then it will leave the last (boundary_len - 1) bytes in its internal buffer, in case they form the start of the boundary string. Thus, len normally needs to be at least 1 byte longer than boundary_len if you want to make any progress at all.

soup_socket_write ()

SoupSocketIOStatus
soup_socket_write (SoupSocket *sock,
                   gconstpointer buffer,
                   gsize len,
                   gsize *nwrote,
                   GCancellable *cancellable,
                   GError **error);

Attempts to write len bytes from buffer to sock . If some data is successfully written, the return status will be SOUP_SOCKET_OK, and *nwrote will contain the number of bytes actually written (which may be less than len ).

If sock is non-blocking, and no data could be written right away, the return value will be SOUP_SOCKET_WOULD_BLOCK. In this case, the caller can connect to the “writable” signal to know when more data can be written. (NB: “writable” is only emitted after soup_socket_write() returns SOUP_SOCKET_WOULD_BLOCK, and it is only emitted once. See the documentation for “non-blocking”.)

The “non-blocking” property

  “non-blocking”             gboolean

Whether or not the socket uses non-blocking I/O.

SoupSocket's I/O methods are designed around the idea of using a single codepath for both synchronous and asynchronous I/O. If you want to read off a SoupSocket, the "correct" way to do it is to call soup_socket_read() or soup_socket_read_until() repeatedly until you have read everything you want. If it returns SOUP_SOCKET_WOULD_BLOCK at any point, stop reading and wait for it to emit the “readable” signal. Then go back to the reading-as-much-as-you-can loop. Likewise, for writing to a SoupSocket, you should call soup_socket_write() either until you have written everything, or it returns SOUP_SOCKET_WOULD_BLOCK (in which case you wait for “writable” and then go back into the loop).

Code written this way will work correctly with both blocking and non-blocking sockets; blocking sockets will simply never return SOUP_SOCKET_WOULD_BLOCK, and so the code that handles that case just won't get used for them.
