Return Values

The Wave API Manager never calls the ACM_Write function, so this routine may be empty and have an arbitrary return value. ACM_Write is a required stream interface driver function, but ACM_IOControl handles all data communication. The ACM Driver Wrapper library (Acmdwrap.lib) always returns 0.
