These macros are for reporting HRESULT errors.

The expression will be evaluated.

If the resulting HRESULT SUCCEEDED then execution will continue normally.
|
|
If the HRESULT FAILED then the macro will return from the current function.

In variants ending with 'M' the given message will be traced when FAILED.

The HR variants will return the HRESULT when FAILED.

The HRB variants will return false when FAILED.

The HRN variants will return NULL when FAILED.
|

The HRV variants will simply return when FAILED.
