Command Code 14h
Valid for: Instance
Description
For SOCK-DGRAM-sockets, this command specifies the peer with which the socket is to be associated (to
which datagrams are sent and the only address from which datagrams are received).
For SOCK_STREAM-sockets, this command attempts to establish a connection to a host.
SOCK_STREAM-sockets may connect successfully only once, while SOCK_DGRAM-sockets may use this
service multiple times to change their association. SOCK-DGRAM-sockets may dissolve their association by
connecting to IP address 0.0.0.0, port 0 (zero).
NON-BLOCKING mode: This command must be issued repeatedly (polled) until a connection is connected, rejected or
timed out. The first connect-attempt will be accepted, thereafter the command will return error
code 22 (EINPROGRESS) on poll requests while attempting to connect.
BLOCKING mode: This command will block until a connection has been established or the connection request is
cancelled due to a timeout or a connection error.
