- * Name: nx_recvmsg
- *
- * Description:
- *   nx_recvmsg() receives messages from a socket, and may be used to
- *   receive data on a socket whether or not it is connection-oriented.
- *   This is an internal OS interface.  It is functionally equivalent to
- *   recvmsg() except that:
- *
- *   - It is not a cancellation point, and
- *   - It does not modify the errno variable.
- *
- * Input Parameters:
- *   sockfd  - Socket descriptor of socket
- *   msg      Buffer to receive the message
- *   flags   - Receive flags
- *
- * Returned Value:
- *   On success, returns the number of characters received.  If no data is
- *   available to be received and the peer has performed an orderly shutdown,
- *   nx_recvmsg() will return 0.  Otherwise, on any failure, a negated errno
- *   value is returned (see comments with recvmsg() for a list of appropriate
- *   errno values).
