* @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
