17
18 The bind routine connects a name (network address) to a socket on the local machine.

22 documentation is available online.
23
24 @param[in] s Socket file descriptor returned from ::socket.
25
26 @param[in] name Address of a sockaddr structure that contains the
27 connection point on the local machine. An IPv4 address
28 of INADDR_ANY specifies that the connection is made to
29 all of the network stacks on the platform. Specifying a
30 specific IPv4 address restricts the connection to the
31 network stack supporting that address. Specifying zero
32 for the port causes the network layer to assign a port
33 number from the dynamic range. Specifying a specific
34 port number causes the network layer to use that port.
35
36 @param[in] namelen Specifies the length in bytes of the sockaddr structure.
37
38 @return The bind routine returns zero (0) if successful and -1 upon failure.
39 In the case of an error, ::errno contains more information.
