The PPB_TCPSocket
interface provides TCP socket operations.
Permissions: Apps permission socket
with subrule tcp-connect
is required for Connect()
; subrule tcp-listen
is required for Listen()
. For more details about network communication permissions, please see: http://developer.chrome.com/apps/app_network.html
Accepts a connection. The socket must be listening.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
[out] | accepted_tcp_socket | Stores the accepted TCP socket on success. |
[in] | callback | A PP_CompletionCallback to be called upon completion. |
- Returns
- An int32_t containing an error code from
pp_errors.h
, including (but not limited to):
PP_ERROR_CONNECTION_ABORTED
: A connection has been aborted.
Binds the socket to the given address. The socket must not be bound.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
[in] | addr | A PPB_NetAddress resource. |
[in] | callback | A PP_CompletionCallback to be called upon completion. |
- Returns
- An int32_t containing an error code from
pp_errors.h
, including (but not limited to):
PP_ERROR_ADDRESS_IN_USE
: the address is already in use.
PP_ERROR_ADDRESS_INVALID
: the address is invalid.
void(* PPB_TCPSocket_1_2::Close)(PP_Resource tcp_socket) |
Cancels all pending operations and closes the socket. Any pending callbacks will still run, reporting PP_ERROR_ABORTED
if pending IO was interrupted. After a call to this method, no output buffer pointers passed into previous Read()
or Accept()
calls will be accessed. It is not valid to call Connect()
or Listen()
again.
The socket is implicitly closed if it is destroyed, so you are not required to call this method.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
Connects the socket to the given address. The socket must not be listening. Binding the socket beforehand is optional.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
[in] | addr | A PPB_NetAddress resource. |
[in] | callback | A PP_CompletionCallback to be called upon completion. |
- Returns
- An int32_t containing an error code from
pp_errors.h
, including (but not limited to):
PP_ERROR_NOACCESS
: the caller doesn't have required permissions.
PP_ERROR_ADDRESS_UNREACHABLE
: addr
is unreachable.
PP_ERROR_CONNECTION_REFUSED
: the connection attempt was refused.
PP_ERROR_CONNECTION_FAILED
: the connection attempt failed.
PP_ERROR_CONNECTION_TIMEDOUT
: the connection attempt timed out.
Since version 1.1, if the socket is listening/connected or has a pending listen/connect request, Connect()
will fail without starting a connection attempt; otherwise, any failure during the connection attempt will cause the socket to be closed.
Creates a TCP socket resource.
- Parameters
-
[in] | instance | A PP_Instance identifying one instance of a module. |
- Returns
- A
PP_Resource
corresponding to a TCP socket or 0 on failure.
Gets the local address of the socket, if it is bound.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
- Returns
- A
PPB_NetAddress
resource on success or 0 on failure.
Gets the remote address of the socket, if it is connected.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
- Returns
- A
PPB_NetAddress
resource on success or 0 on failure.
Determines if a given resource is a TCP socket.
- Parameters
-
[in] | resource | A PP_Resource to check. |
- Returns
PP_TRUE
if the input is a PPB_TCPSocket
resource; PP_FALSE
otherwise.
Starts listening. The socket must be bound and not connected.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
[in] | backlog | A hint to determine the maximum length to which the queue of pending connections may grow. |
[in] | callback | A PP_CompletionCallback to be called upon completion. |
- Returns
- An int32_t containing an error code from
pp_errors.h
, including (but not limited to):
PP_ERROR_NOACCESS
: the caller doesn't have required permissions.
PP_ERROR_ADDRESS_IN_USE
: Another socket is already listening on the same port.
Reads data from the socket. The socket must be connected. It may perform a partial read.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
[out] | buffer | The buffer to store the received data on success. It must be at least as large as bytes_to_read . |
[in] | bytes_to_read | The number of bytes to read. |
[in] | callback | A PP_CompletionCallback to be called upon completion. |
- Returns
- A non-negative number on success to indicate how many bytes have been read, 0 means that end-of-file was reached; otherwise, an error code from
pp_errors.h
.
Sets a socket option on the TCP socket. Please see the PP_TCPSocket_Option
description for option names, value types and allowed values.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
[in] | name | The option to set. |
[in] | value | The option value to set. |
[in] | callback | A PP_CompletionCallback to be called upon completion. |
- Returns
- An int32_t containing an error code from
pp_errors.h
.
Writes data to the socket. The socket must be connected. It may perform a partial write.
- Parameters
-
[in] | tcp_socket | A PP_Resource corresponding to a TCP socket. |
[in] | buffer | The buffer containing the data to write. |
[in] | bytes_to_write | The number of bytes to write. |
[in] | callback | A PP_CompletionCallback to be called upon completion. |
- Returns
- A non-negative number on success to indicate how many bytes have been written; otherwise, an error code from
pp_errors.h
.
