|
|
// The return value of COM functions and methods is an HRESULT.
|
|
// This is not a handle to anything, but is merely a 32-bit value
|
|
// with several fields encoded in the value. The parts of an
|
|
// HRESULT are shown below.
|
|
//
|
|
// Many of the macros and functions below were orginally defined to
|
|
// operate on SCODEs. SCODEs are no longer used. The macros are
|
|
// still present for compatibility and easy porting of Win16 code.
|
|
// Newly written code should use the HRESULT macros and functions.
|
|
//
|
|
// HRESULTs are 32 bit values layed out as follows:
|
|
//
|
|
// 3 3 2 2 2 2 2 2 2 2 2 2 1 1 1 1 1 1 1 1 1 1
|

// S - Severity - indicates success/fail

// 0 - Success

// 1 - Fail (COERROR)

// R - reserved portion of the facility code, corresponds to NT's

// C - reserved portion of the facility code, corresponds to NT's

// C field.
|

//
|
|
// N - reserved portion of the facility code. Used to indicate a
|
|
// mapped NT status value.
|
|
//
|
|
// r - reserved portion of the facility code. Reserved for internal
|
|
// use. Used to indicate HRESULT values that are not status
|
|
// values, but are instead message ids for display strings.
|
|
//
|
|
// Facility - is the facility code
|
|
//
|
|
// Code - is the facility's status code
