g2intg2_gribend(unsignedchar*cgrib)
       Finalize a GRIB2 message after all grids and fields have been added. This function 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.

       Parameterscgrib 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.

           • G2_GRIBEND_MSG_INIT GRIB message was not initialized - call g2_create() first.

           • G2_BAD_SEC_COUNTS Sum of Section byte counts doesn't add to total byte count.

           • G2_BAD_SEC 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.
