Function `dmd.target.Target.applyInRefParams`

Determine which in parameters needs to be passed by ref


						
				extern(C++) void applyInRefParams
				(
				

				  TypeFunction tf
				

				);

Called from TypeFunction semantic with the full function type. This routine must iterate over parameters, and may set STC.ref_ for any parameter which already have STC.in_. This hook must never set STC.ref_ if the parameter is not STC.in_, nor should it ever change anything else.

This hook will not be called when -preview=in wasn't passed to the frontend, hence it needs not care about global.params.previewIn.

Parameters

Name	Description
tf	Type of the function to inspect. The type will have its parameter types semantically resolved, however other attributes (return type, `@safe` / `nothrow`, etc...) must not be used.
