GetLastError()?

[vefatica]

In general, will I get accurate results calling GetLastError() after a TCC/SDK API fails?

In particular, how about AllocMem()? ... as in

LPVOID p = AllocMem(size);
if ( p == NULL )
    return error(GetLastError(), L"AllocMem");

In general, but not for APIs that don't call Windows, and not for APIs that
call Windows but then call another Windows API after the first one fails.

But not for AllocMem(), which doesn't call Windows (except for the first
allocation).

The only way AllocMem() will fail is if Windows is out of memory.
