The client connection and the server listener sockets used largely similar code. Combining them allows for simpler protocol code. Cleaned up parts of the DCB listener creation and moved the parsing of the network binding configuration to a higher level.

* @brief Create a network socket and a socket configuration
|
|
*
|
|
* This helper function can be used to open both listener socket and network
|
|
* connection sockets. For listener sockets, the @c host and @c port parameters
|
|
* tell where the socket will bind to. For network sockets, the parameters tell
|
|
* where the connection is created.
|
|
*
|
|
* After calling this function, the only thing that needs to be done is to
|
|
* give @c addr and the return value of this function as the parameters to
|
|
* either bind() (for listeners) or connect() (for outbound network connections).
|
|
*
|
|
* @param type Type of the socket, either MXS_SOCKET_LISTENER for a listener
|
|
* socket or MXS_SOCKET_NETWORK for a network connection socket
|
|
* @param addr Pointer to a struct sockaddr_storage where the socket
|
|
* configuration is stored
|
|
* @param host The target host for which the socket is created
|
|
* @param port The target port on the host
|
|
*
|
|
* @return The opened socket or -1 on failure
