Example 22. Split Object Component Driver

#include <cpy_tbl.h>

extern far COPY_TABLE task13_ctbl;
extern far COPY_TABLE task47_ctbl;

extern void task1(void);
...
extern void task7(void);

main()
{
   ...
   copy_in(&task13_ctbl);
   task1();
   task2();
   task3();
   ...

   copy_in(&task47_ctbl);
   task4();
   task5();
   task6();
   task7();
   ...
}

You must declare a COPY_TABLE object as far to allow the overlay copy table section placement to be independent from the other sections containing data objects (such as .bss).

The contents of the .task1to3 section are split in the section's load space and contiguous in its run space. The linker-generated copy table, _task13_ctbl, contains a separate COPY_RECORD for each piece of the split section .task1to3. When the address of _task13_ctbl is passed to copy_in(), each piece of .task1to3 is copied from its load location into the run location.

The contents of the GROUP containing tasks 4 through 7 are also split in load space. The linker performs the GROUP split by applying the split operator to each member of the GROUP in order. The copy table for the GROUP then contains a COPY_RECORD entry for every piece of every member of the GROUP. These pieces are copied into the memory overlay when the _task47_ctbl is processed by copy_in().

The split operator can be applied to an output section, GROUP, or the load placement of a UNION or UNION member. The linker does not permit a split operator to be applied to the run placement of either a UNION or of a UNION member. The linker detects such violations, emits a warning, and ignores the offending split operator usage.
