System.Threading.AccessControl
Blittable version of Windows BOOL type. It is convenient in situations where
manual marshalling is required, or to avoid overhead of regular bool marshalling.
Some Windows APIs return arbitrary integer values although the return type is defined
as BOOL. It is best to never compare BOOL to TRUE. Always use bResult != BOOL.FALSE
or bResult == BOOL.FALSE .
Returns a string message for the specified Win32 error code.
Provides static methods for converting from Win32 errors codes to exceptions, HRESULTS and error messages.
Converts, resetting it, the last Win32 error into a corresponding object, optionally
including the specified path in the error message.
Converts the specified Win32 error into a corresponding object, optionally
including the specified path in the error message.
If not already an HRESULT, returns an HRESULT for the specified Win32 error code.
Returns a Win32 error code for the specified HRESULT if it came from FACILITY_WIN32
If not, returns the HRESULT unchanged
