This function initiates a connection on a socket.
    If s is a socket descriptor of type SOCK_DGRAM, then this call
    permanently specifies the peer where the data is sent. If s is of
    type SOCK_STREAM, then this call attempts to make a connection to
    the specified socket.
    If a call to connect() fails for a connection-mode socket,
    applications should use close() to deallocate the socket
    and descriptor. If attempting to reinitiate the connection,
    applications should create a new socket.
