\label{gGEMSt_8h_a0}


Sends a dataless command to the GEM Statistics register block. 

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em gdab}]gdab\-Handle containing the COM I/O (gnat) handle \item[{\em opcode}]opcode of command to send \end{description}
\end{Desc}
\begin{Desc}
\item[Returns:]G\_\-OK on success\end{Desc}
Sends the dataless command specified by {\em opcode\/} to the GEM. \hypertarget{gGEMSt_8h_a1}{

\label{gGEMSt_8h_a1}


Reads a register returing value in {\em val\/}. 

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em gdab}]gdab\-Handle containing the COM I/O (gnat) handle \item[{\em reg}]register to read \item[{\em val}]pointer to storage to hold the response of the read command \end{description}
\end{Desc}
\begin{Desc}
\item[Returns:]G\_\-OK on success\end{Desc}
Reads the {\em reg\/} from the GEM Statistics register block. {\em val\/} is filled on return.

The following error codes are returned when LATp errors occur:

\begin{itemize}
\item GERR\_\-LATP\_\-HEADER\_\-PARITY \item GERR\_\-LATP\_\-CELL\_\-PARITY \item GERR\_\-LATP\_\-TRUNCATE \end{itemize}
