Метод OsErrorToException

Кстати, для того чтобы перекодировать значение, возвращаемое функцией GetLastError(), в код причины, вызвавшей прерывание, можно использовать метод OsErrorToException(), исходный код которого находится в файле filex.cpp:

int PASCAL CFileException::OsErrorToException(LONG lOsErr)

{

// NT Error codes switch ((UINT)lOsErr)

{
