Function Documentation

   gtemplate* extgridtemplate (g2int number, g2int * list)
       This subroutine generates the remaining octet map for a given Grid Definition Template, if
       required. Some Templates can vary depending on data values given in an earlier part of the
       Template, and it is necessary to know some of the earlier entry values to generate the
       full octet map of the Template.

       • 2008-07-08 Vuong Added GDT 3.32768 Rotate Lat/Lon E-grid (Arakawa)

       • 2009-01-14 Vuong Changed structure name template to gtemplate

       • 2010-05-11 Vuong Added GDT 3.32769 Rotate Lat/Lon Non-E Staggered grid (Arakawa)

       • 2013-08-06 Vuong Added GDT 3.4,3.5,3.12,3.101,3.140

       Parameters
           number NN, indicating the number of the Grid Definition Template 3.NN that is being
           requested.
           list The list of values for each entry in the Grid Definition Template.

       Returns
           Pointer to the returned template struct. Returns NULL pointer, if template not found.

   gtemplate* getgridtemplate (g2int number)
       This subroutine returns grid template information for a specified Grid Definition Template
       3.NN. The number of entries in the template is returned along with a map of the number of
       octets occupied by each entry. Also, a flag is returned to indicate whether the template
       would need to be extended.
