socket.CMSG_LEN() - socket

Return the total length, without trailing padding, of an ancillary
data item with associated data of the given length.  This value
can often be used as the buffer size for recvmsg() to
receive a single item of ancillary data, but RFC 3542 requires
portable applications to use CMSG_SPACE() and thus include
space for padding, even when the item will be the last in the
buffer.  Raises OverflowError if length is outside the
permissible range of values.
