/**
Bind a name to a socket.
The bind routine connects a name (network address) to a socket on the local machine.
The
<a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/bind.html">POSIX</a>
documentation is available online.
@param[in] s Socket file descriptor returned from ::socket.
@param[in] name Address of a sockaddr structure that contains the
connection point on the local machine. An IPv4 address
of INADDR_ANY specifies that the connection is made to
all of the network stacks on the platform. Specifying a
specific IPv4 address restricts the connection to the
network stack supporting that address. Specifying zero
for the port causes the network layer to assign a port
number from the dynamic range. Specifying a specific
port number causes the network layer to use that port.
@param[in] namelen Specifies the length in bytes of the sockaddr structure.
@return The bind routine returns zero (0) if successful and -1 upon failure.
In the case of an error, ::errno contains more information.
