bind()

bind a name to a socket

Synopsis:

#include <sys/types.h>
#include <sys/socket.h>

int bind( int s,
          const struct sockaddr *name,
          int namelen );

Description:

When a socket is created with socket(), it exists in a namespace (address family) but has no name assigned to it. The bind() function assigns a name to that unnamed socket.

The bind() function assigns a local address. Use connect() to assign a remote address.

The rules used for binding names vary between communication domains.

Returns:

0: Success.
-1: An error occurred; errno is set.

Errors:

If an error occurred, errno could contain one of the following:

EACCES: The requested address is protected, and the current user has inadequate permission to access it.
EADDRINUSE: The specified address is already in use.
EADDRNOTAVAIL: The specified address isn't available from the local machine.
EBADF: s isn't a valid descriptor.
EFAULT: The name parameter isn't in a valid part of the user address space.
EINVAL: The socket is already bound to an address.
