Module Name:
FusionHandle.h
Abstract:
Simple exception safe wrappers of Win32 "handle" types, defining "handle" loosely.
CFusionFile
CDynamicLinkLibrary
CFindFile (should be named CFindFileHandle, see NVseeLibIo::CFindFile vs. NVseeLibIo::CFindFileHandle
CFindFile includes a WIN32_FIND_DATA, CFindFileHandle does not.)
CFileMapping
CMappedViewOfFile
CRegKey
See also:
NVseeLibReg::CRegKey
NVseeLibIo::CFusionFile
NVseeLibIo::CFileMapping
NVseeLibIo::CMappedViewOfFile
NVseeLibIo::CFindFullPath
NVseeLibModule::CDynamicLinkLibrary
etc.
