/*
* M A P I W I N . H
*
* Definitions used by the MAPI Development Team to aid in
* developing single-source service providers that run on
* both WIN32 and WIN16 platforms.
* There are three sections.
*
* The first section defines how to call something that
* is available by different methods in WIN16 vs. WIN32.
* As such, they are totally new mechanisms.
*
* The second section establishes things that are available
* AS-IS in one environment but we have to define for the
* other environment.
*
* The third section simply defines a few conventions
* (simplifications) for common operations.
*

/*
* Routines are included in the first section to manage per-instance
* global variables for DLLs. They assume that all of the DLL's
* per-instance global variables live in a single block of memory.
* Functions are provided to install and retrieve the correct block of
* memory for the current instance.
*
* There are only two functions:
*
* PvGetInstanceGlobals Call this to get the address of the
* per-instance globals structure.
* ScSetinstanceGlobals Call this to install the
* per-instance globals structure. It
* may fail if the number of instances
* exceeds a certain limit.
*
* The caller is free to choose the name, size, and allocation
* method of the per-instance global variables structure.
*
* The WIN32 implementation uses a pointer in the DLL's data
* segment. This assumes that the DLL gets a separate instance
* of the default data segment per calling process.
*
* The WIN16 implementation uses a fixed array of pointers and a
* matching fixed array of keys unique to the calling process.
*/
/*
* The second section consists largely of Win32 file I/O functions
* that are not supported under Win16. These functions are
* implemented in mapiwin.c, using DOS calls. Most have limitations
* relative to their Win32 counterparts, which are spelled out in
* the comments to the source code.
