function DynArrayCopy()

Unit mormot.core.rtti

Function DynArrayCopy() is defined as follows:

procedure DynArrayCopy(Dest, Source: PPointer; Info: PRttiInfo; SourceExtCount: PInteger);

Why not define it this way?

procedure DynArrayCopy(Dest, Source: PPointer; Info: PRttiInfo; SourceExtCount: PInteger = Nil);

I only noticed after viewing the source that it could also be Nil.

With best regards
Thomas

Re: function DynArrayCopy()

This is a very low-level function. The idea is to rather use TDynArray, or just the standard copy() function, which does not require a TypeInfo() parameter.
