RefOrNull1 method

Pointer<Char> RefOrNull1(
  1. String? o
)

Writes o into slot '1' and returns its pointer, or returns nullptr if o is null.

Use this instead of Ref1 when the C API uses a null pointer to signal "no value".

Implementation

Pointer<Char> RefOrNull1(String? o) => o == null ? nullptr : Ref1(o);
