[news.eclipse.dsdp.rtsc] Finding out the size of the structure in xs fil

[ravindranath.a@xxxxxx (Ravindranath )]

Is there a way to find out the size of the structure (declared in xdc 
file) 
in module's xs file.
for example  i have  a structure
like below in xdc file

module xdc file

struct entry
{
    UInt32 a;
    uinon {
       UInt8 b;
       UInt32 c;
    }
};


In xs file i have to  know the size of <mod>_entry structure size.

How do i do this. Please let me know if any body knows  how to do it?.
