Function Documentation

   g2int g2_gribend (unsigned char * cgrib)
       This routine finalizes a GRIB2 message after all grids and fields have been added. It adds
       the End Section ('7777') to the end of the GRIB message and calculates the length and
       stores it in the appropriate place in Section 0. This routine is used with routines
       g2_create(), g2_addlocal(), g2_addgrid(), and g2_addfield() to create a complete GRIB2
       message. g2_create() must be called first to initialize a new GRIB2 message.

       Parameters
           cgrib Char array containing all the data sections added be previous calls to
           g2_create, g2_addlocal, g2_addgrid, and g2_addfield. After function is called,
           contains the finalized GRIB2 message.

       Returns

           • > 0 = Length of the final GRIB2 message in bytes.

           • -1 = GRIB message was not initialized. Need to call routine g2_create first.

           • -2 = GRIB message already complete.

           • -3 = Sum of Section byte counts doesn't add to total byte count

           • -4 = Previous Section was not 7.

       Note
           This routine is intended for use with routines g2_create(), g2_addlocal(),
           g2_addgrid(), and g2_addfield() to create a complete GRIB2 message.
