static void PrepareContextToReceiveMembers ( TypeSystemClang &  ast, ClangASTImporter &  ast_importer, clang::DeclContext *  decl_ctx, DWARFDIE  die, const char *  type_name_cstr  )

static

This function ensures we are able to add members (nested types, functions, etc.) to this type.

It does so by starting its definition even if one cannot be found in the debug info. This means the type may need to be "forcibly completed" later – see CompleteTypeFromDWARF).
