{\tt ox\_pop\_cmo()} receives the data on the stack of a server. |
|
{\tt ox\_cmo\_rpc()} requests a server to execute a function. |
|
{\tt ox\_reset()} completes |
|
the operations stated in Section \ref{control}. |
|
{\tt ox\_select()} is provided to detect if streams are ready for |
|
reading to avoid blocking on read operations. |
|
|
\begin{itemize} |
|
\item {\tt ox\_pop\_cmo()} |
|
|
|
It requests a server to send data on the stack to the stream, then |
|
it receives the data from the stream. |
|
|
|
\item {\tt ox\_cmo\_rpc()} |
|
|
|
After pushing the name of a function, arguments and the number of the |
|
arguments to the stack of a server, it requests the server to execute |
|
the function. It does not wait the termination of the function call. |
|
|
|
\item {\tt ox\_reset()} |
|
|
|
After sending {\tt SM\_control\_reset\_connection} to a control server, |
|
it completes the operations stated in Section \ref{control}. |
|
\end{itemize} |
|
Furthermore {\tt ox\_select()} is provided to detect if streams are ready for |
|
reading. It is implemented by the {\tt select()} system call and is used |
|
to avoid blocking on read operations. |
