Function Documentation

   gtemplate* extdrstemplate (g2int number, g2int * list)
       This subroutine generates the remaining octet map for a given Data Representation
       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.

       Parameters
           number NN, indicating the number of the Data Representation Template 5.NN that is
           being requested.
           list The list of values for each entry in the the Data Representation Template 5.NN.

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

   gtemplate* getdrstemplate (g2int number)
       This subroutine returns DRS template information for a specified Data Representation
       Template 5.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.
