\label{gGEMMG_8h_a0}


Loads a register with value. 

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em gdab}]gdab\-Handle containing the COM I/O (gnat) handle \item[{\em reg}]register to load \item[{\em value}]32-bit value to load \end{description}
\end{Desc}
\begin{Desc}
\item[Returns:]G\_\-OK on success\end{Desc}
Loads the register {\em reg\/} from the GEM Trigger Accept Message register block with {\em value\/} \hypertarget{gGEMMG_8h_a1}{
\index{gGEMMG.h@{g\-GEMMG.h}!gGEMMGread@{gGEMMGread}}

\label{gGEMMG_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 register {\em reg\/} from the GEM Trigger Accept Message 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}
