RDCore.SDK.Runtime.Abstract.StdLib
Assembly
RDCore.SDK.dll

States that a standard-library parameter is ByRef … As Any, as a Declare's can be: it takes a variable of any type but an array, and the member is given where the variable is - its address in the session's memory - rather than what it holds.

Remarks

The parameter is declared as a VBLongLongValue, whatever the width of the environment's pointers: what it is given is

  • the address of a variable passed to it;
  • the address of a temporary, for what is no variable (a literal, an expression, what a function returns), which is freed when the statement that passes it is over;
  • the bytes a ByVal argument is stored in, read as a whole number - which is how MS-VBA passes it (recorded in Excel): a whole number is itself, a Double its bits, a Variant its VARIANT's type.
VarPtr is declared so, as the VBA type library declares it: VarPtr(Ptr As Any) As LongPtr.
