\label{siis2moc_8c_a22}


Write a CCSDS packet and packet annotation header to a level 0 MOC file. There is a separate file for each APID/VCID. The file is created if this is the first packet for a given file.

\begin{Desc}
\item[Parameters:]
\begin{description}
\item[{\em pdu\_\-hdr}]Pointer to packet annotation header information. \item[{\em data}]Pointer to start of the packet buffer. \item[{\em data\_\-bytes}]Number of bytes of data in the packet buffer. \item[{\em apid}]APID for the packet. \item[{\em length}]Length of the packet, in bytes, as reported in its header.\end{description}
\end{Desc}
\begin{Desc}
\item[Returns:]A SIIS MSG value. \end{Desc}
