Record Parameter Passing in C++

What is translated > Routines > Parameter types > Record Parameter Passing in C++

Passing a record by value is a special case.

In Delphi, records passed by value can be modified inside a routine, but such modifications do not affect the caller.

To reproduce this behavior correctly in C++, Delphi2Cpp passes the record as a constant reference, and then creates a local copy inside the routine.

This approach avoids unnecessary copying at the call site while preserving Delphi’s semantics.

Example:

void Foo(const MyRecord& cparam)

{

    MyRecord param = cparam;

    // Use 'param' instead of 'cparam' to allow modification

}

The original parameter is renamed (to cparam) to avoid naming conflicts.
