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 \fBg2_create()\fP, \fBg2_addlocal()\fP, \fBg2_addgrid()\fP, and \fBg2_addfield()\fP to create a complete GRIB2 message\&. \fBg2_create()\fP must be called first to initialize a new GRIB2 message\&.
.PP
\fBParameters\fP
.RS 4
\fIcgrib\fP 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\&.

\fBReturns\fP
.RS 4
.IP "\(bu" 2
> 0 = Length of the final GRIB2 message in bytes\&.
.IP "\(bu" 2
-1 = GRIB message was not initialized\&. Need to call routine g2_create first\&.
.IP "\(bu" 2
-2 = GRIB message already complete\&.
.IP "\(bu" 2
-3 = Sum of Section byte counts doesn't add to total byte count
.IP "\(bu" 2
-4 = Previous Section was not 7\&.

\fBNote\fP
.RS 4
This routine is intended for use with routines \fBg2_create()\fP, \fBg2_addlocal()\fP, \fBg2_addgrid()\fP, and \fBg2_addfield()\fP to create a complete GRIB2 message\&.
