Function/Subroutine Documentation

subroutine addgrid	(	character(len=1), dimension(lcgrib), intent(inout)	cgrib,
		integer, intent(in)	lcgrib,
		integer, dimension(*), intent(in)	igds,
		integer, dimension(*), intent(in)	igdstmpl,
		integer, intent(in)	igdstmplen,
		integer, dimension(idefnum), intent(in)	ideflist,
		integer, intent(in)	idefnum,
		integer, intent(out)	ierr
	)

This routine is used with routines gribcreate(), addlocal(), addfield(), and gribend() to create a complete GRIB2 message.

Subroutine gribcreate must be called first to initialize a new GRIB2 message.

Parameters

[in,out]	cgrib	Character array to contain the GRIB2 message
[in]	lcgrib	Maximum length (bytes) of array cgrib.
[in]	igds	Contains information needed for GRIB Grid Definition Section 3. Must be dimensioned >= 5. igds(1)=Source of grid definition (see Code Table 3.0) igds(2)=Number of grid points in the defined grid. igds(3)=Number of octets needed for each additional grid points definition.Used to define number of points in each row ( or column ) for non-regular grids. = 0, if using regular grid. igds(4)=Interpretation of list for optional points definition. (Code Table 3.11) igds(5)=Grid Definition Template Number (Code Table 3.1)
[in]	igdstmpl	Contains the data values for the specified Grid Definition Template ( NN=igds(5) ). Each element of this integer array contains an entry (in the order specified) of Grid Defintion Template 3.NN
[in]	igdstmplen	Max dimension of igdstmpl()
[in]	ideflist	(Used if igds(3) .ne. 0) This array contains the number of grid points contained in each row ( or column )
[in]	idefnum	(Used if igds(3) .ne. 0) The number of entries in array ideflist. i.e. number of rows ( or columns ) for which optional grid points are defined.
[out]	ierr	Error return code. 0 = no error 1 = GRIB message was not initialized. Need to call routine gribcreate first. 2 = GRIB message already complete. Cannot add new section. 3 = Sum of Section byte counts doesn't add to total byte count. 4 = Previous Section was not 1, 2 or 7. 5 = Could not find requested Grid Definition Template.

Note: : Note that the Local Use Section ( Section 2 ) can only follow Section 1 or Section 7 in a GRIB2 message.
