\subsection{NXUTIL}
Ther are some utility functions for  writing NeXus data files from
SICS with the NXDICT-API. These are collected in the files nxutil.h
and nxutil.c.

\begin{description}
\item[int SNXSPutMotor(SicsInterp *pSics, SConnection *pCon, NXhandle hFil,
                   NXdict pDict, char *pAlias, char *pName)] writes the
value of a motor to file. The parameters are: \begin{description}
   \item[pSics] The SICS interpreter to search for the motor.
   \item[pCon] The connection object to which to print errors.
   \item[hFil] The handle of the NeXus file to write.
   \item[pDict] The handle of the NeXus dictionary to use.
   \item[pAlias] The alias name to use for writing.
   \item[pName] The name of the motor.
   \end{description} 
\item[SNXSPutMotorNULL] writes the motor zero point. Same parameters
as above. 
\item[int SNXSPutVariable(SicsInterp *pSics, SConnection *pCon,\\
                      NXHandle hFil, NXdict pDict, char *pAlias,\\
                      char *pName)] writes a SICS variable to a NeXus file
using the dictionary. Parameters similar to SNXSPutMotor.
\item[SNXSPutEVVar(NXhandle hfil,NXdict pDict,char *pName, SConnection
                      *pCon,\\  char *pValAlias, char *pStddevAlias)]
This writes an environment variable pName to the file described by hfil,
using the dictionary pDict. A warning is printed if the variable is
not configured. If a variable is found its value and standard
deviation are written to file using the aliases given as parameters. 
\item[SNXSPutGlobals] writes global data to the file.
\item[SNXSFormatTime] returns the current time formatted according to
the NeXus specification in buffer. Max iLen characters will be copied
to buffer. 
\item[SNXSMakeFileName] returns a pointer to a buffer containing a new
file name for a data file. This function assembles the filename from
the DataNUmber and various SICS variables. The caller has to free the
buffer containg the name. 
\item[SNXSPutDrivable] writes any  variable adhering to the drivable
interface.
