# no_implementation import attribute

**C++ Specific**

Suppresses the generation of the `.tli` header, which contains the implementations of the wrapper member functions.

## Syntax

> **#import** *type-library* **no_implementation**

## Remarks

If this attribute is specified, the `.tlh` header, with the declarations to expose type-library items, will be generated without an `#include` statement to include the `.tli` header file.

This attribute is used in conjunction with [implementation_only](../preprocessor/implementation-only.md).
