1. The macros are defined in dutil.h
2. Typically, when dealing with Win32 APIs that return BOOL and set last
error, the pattern looks like this:
if (!::Win32ApiThatReturnsFalseOnError(param, param2))
{
ExitWithLastError(hr, "Failed to do what Win32 API was supposed to
do.");
}
Actually, "dutil.lib" is our collection of helper functions that standardize
all APIs on HRESULTs. Typically, if there is a Win32 API and it's needed in
deployment "deployment utillity library" (dutil.lib) probably has it.
