// ACM General API's and Defines
//
//--------------------------------------------------------------------------
// there are four types of 'handles' used by the ACM. the first three
// are unique types that define specific objects:
//
// HACMDRIVERID: used to _identify_ an ACM driver. this identifier can be
// used to _open_ the driver for querying details, etc about the driver.
//
// HACMDRIVER: used to manage a driver (codec, filter, etc). this handle
// is much like a handle to other media drivers--you use it to send
// messages to the converter, query for capabilities, etc.
//
// HACMSTREAM: used to manage a 'stream' (conversion channel) with the
// ACM. you use a stream handle to convert data from one format/type
// to another--much like dealing with a file handle.
//
//
// the fourth handle type is a generic type used on ACM functions that
// can accept two or more of the above handle types (for example the
// acmMetrics and acmDriverID functions).
//
// HACMOBJ: used to identify ACM objects. this handle is used on functions
// that can accept two or more ACM handle types.
