Which code is calling var_system function and how
calling code will tell it is set request to the function var_system so
that var_system will set up the write_method hook value, here what is
hook value to invoke the SET processing code for that object.

It doesn't.
The var_system function is called in an identical fashion for both
a GET request and a SET request.

It doesn't know whether this is a GET or a SET request,
so it should return the appropriate 'write_method' hook
routine.

The var_system routine doesn't know whether this is a GET
or a SET request. But the code that *calls* the var_system
routine does.
So var_system will set up the write_method hook value,
just in case this is a SET request. If it is, then the agent
driving code will use this hook value to invoke the SET
processing code for that object.
If this is actually a GET request, then the agent driving
code will simply ignore the 'write_method' value.
