	DPMI Error Codes
		A DPMI 1.0 host signals an error by returning from a function with the Carry flag set and an error code in AX.
		If the error code has bit 15 clear (0), the DPMI host is passing a DOS error code through to the client; for a list of these error codes, consult a DOS technical reference.
		All DPMI 1.0 hosts are required to check for the error conditions listed in this specification, and must return the error codes that are documented for each function.

	About DPMI
		DPMI is also used by DJGPP programs to allocate memory, set interrupt vectors, and perform protected-mode to real-mode (and vice-versa) interrupt call translations.
		DPMI is a standardized interface that provides interrupt-level functions for things such as switching between real and protected mode, allocating memory, and setting interrupt vectors.
		However, DPMI isn't available; we'd have to implement all of its functionality by manipulating control registers on the processor and building various data structures by hand.

	DPMI Specification Available from Intel
		The DPMI specification was defined to allow an MS-DOS program to access the extended memory provided by a PC architecture computer while maintaining system protection.
		DPMI is commonly used to communicate with a terminate-and-stay- resident (TSR) program or an MS-DOS device driver from a protected mode application.
		DPMI services should be used only in a Windows device driver or a dynamic-link library (DLL).

	VOGONS :: View topic - DOSBOX and DPMI
		Since DPMI is also supported in newer operating systems (Windows), it means that properly written DOS applications can work there as well.
		DPMI can be used directly or indirectly (by DOS extenders like DOS4GW.EXE - this feature enables those games to work in Windows).
		I tested it by DPMI testing utilities after starting it by RTMRES.EXE and it seemed ok. It did not work with Ultima 8, but this could be some game specific problem.

	DPMI 0.9: General Notes for Protected Mode Programs
		While DPMI defines a specific set of functions that will be supported by all implementations, there may be minor differences in individual implementations.
		DPMI will automatically provide a real mode stack for interrupts that are reflected to real mode.
		Some DPMI implementations will not call DOS to read or write virtual memory to disk and under these implementations the page locking services may be ignored.

	Dr. Dobb's \| DPMI Meets C++ \| October 1, 1992
		DPMI does a decent job of abstracting the processor's protected-mode capabilities, and assembly language is the appropriate level for its specification.
		The class library is designed to allow the same level of control that the raw DPMI interface allows, and at the same time make it easy to do common operations like allocation of an addressable block of memory, modification of individual attributes of segments, and release of memory and descriptors back to the host.
		DPMI allows programmers to obtain an ordered set of descriptors that can be set up to span a partition of memory larger than 64 Kbytes--an important capability for addressing huge objects in 16-bit mode.

	[discuss] DPMI on AMD64
		But in any case such a function will not be provided by DPMI itself, but rather by the environment that runs over DPMI (usually a DOS extender).
		If the app does not intend "dirty" things (in which case I believe there are not much things that may be done), then all the code that have to run in real/V86 mode, including the code that execute initially and switch to PM, will be in the DOS extender part, not in the app.
		The bad thing is that for most app, the time spent in real/V86 mode (including the time used for switching) is already a noticeable part of the total time, so if this get emulated (or virtualized), performance will become...

	DPMI Specification
		Because DPMI hosts switch stacks automatically across mode switches, it is sometimes necessary to use the state save/restore functions while using the raw mode switch services.
		Under DPMI implementations that support virtual memory, it is important to consider issues such as the amount of available physical memory.
		Under DPMI implementations that do not use the 80386 paging mechanism, the function will always succeed and the address returned will be equal to the physical address parameter passed into this function.

		Mostly for fun, i've been experimenting around with the DPMI, but every corner i turn seems to be a brick wall....
		It's not a true restriction for a 16-bit dpmi client, which could handle 4 GB segments as well (if it is running on a 80386+).
		However, in a windows dos box, the dpmi host also includes a "dos extender" (which allows to directly call int 21h with pointers involved), and these extenders will ignore the HIWORD of any offsets for 16bit clients.

		It was my understanding that when using DPMI to do DOS extended progrmming, you have the total system memory span and no paging (like in Expanded Memory paging) is needed.
		But i guess memory management is really dependent on the kind of DPMI server you are using.
