[fpc-pascal] record helpers how they effect records
using a simple record, e.g. some_record_type = record a, b : longint; end; If I declare a record helper, does this change the record in any way? i.e. does the record take any more space when passed as a function parameter? Does it become somehow like an object, and need to be allocated? Or is the helper more like a language shortcut/convenience, where the compiler still treats the record the same way, and declaring and using the helper is equivalent to declaring and using a function that takes the record as a parameter? I'm using mode objfpc Thanks! ~David ___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal

I'd like to extend the question to class helpers, i.e., declaring and using the helper is equivalent to declaring and using a function that takes the class instance as a parameter?

Yes, this is correct. It's syntactical sugar. The basic layout of a record is not changed.

Yes, with the proviso that the scoping rules are somewhat different. Michael.___ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
