SafeHandleMinusOneIsInvalid

Provides a base class for Win32 safe handle implementations in which the value of -1 indicates an invalid handle.

SafeHandleZeroOrMinusOneIsInvalid

Provides a base class for Win32 safe handle implementations in which the value of either 0 or -1 indicates an invalid handle.

SafeMemoryMappedFileHandle

Provides a safe handle that represents a memory-mapped file for sequential access.

SafeMemoryMappedViewHandle
