Using Predefined Data Structures

union name, u_zcntntstype; on line 19, the name of the union structure containing

the desired field, zdoctype; on line 10, the name of the field in zdoctype,

zdoctypename.

Line 10 also shows that zdoctypename is defined as zaps_ddl_obj_id_def,

which is specified in the file ZAPSC. The zaps_ddl_obj_id structure corresponds

to the ASN.1-type object identifier and is broken down into the count of elements in the

object identifier array (maximum of 16) and the components of the object identifier.

The file ZAPSC shows this C data structure for zaps_ddl_obj_id_def, again with

comments removed:

1 #pragma section zaps_ddl_obj_id

2 typedef struct

3 {

4 zaps_ddl_int1_def znum_elements;

5 zaps_ddl_int1_def zobj_id[16];

6 } zaps_ddl_obj_id_def;

Therefore, to set up the document type name for an FTAM-3 file, use these lines of C

code:

contents_type.u_zcntntstype.zdoctype.zdoctypename.znum_elements = 5;

contents_type.u_zcntntstype.zdoctype.zdoctypename.zobj_id [0] = 1;

contents_type.u_zcntntstype.zdoctype.zdoctypename.zobj_id [1] = 0;

contents_type.u_zcntntstype.zdoctype.zdoctypename.zobj_id [2] = 8571;

contents_type.u_zcntntstype.zdoctype.zdoctypename.zobj_id [3] = 5;

contents_type.u_zcntntstype.zdoctype.zdoctypename.zobj_id [4] = 3;
