|
|
// Abstract:
|
|
// Contains the definition of the IImgErrorInfo interface used to describe
|
|
// extra error state. This inherits from the COM IErrorInfo interface.
|
|
//
|
|
// Notes:
|
|
// IImgErrorInfo stores its state in an ImgErrorInfo structure that can
|
|
// be detached from the class implementation. IImgErrorInfo is NOT thread
|
|
// safe.
|
|
//
|
|
// History:
|
|
// 2003/10/20-mlawrenc
|
|
// Created - removed from imgdata.idl to provide better sanitization
|
|
// from the rest of the imgdata interface, also in prepartaion
|
|
// of moving to Musl.
