Aug-27-1991:
NOTE (Yarons):
This is the 32 bit support as of April 1st 1990 - by stevewo
For 32 bit APIs, we added named pipes, fixed bugs and support UNC.
Bulk of work and focus is on 16bit APIs, which is scheduled in a Win
Project file with WIN32/NT product 1 schedule
--------------------------------------------------------------------
; This list defines the Cruiser OS/2 API Calls that are supported by the
; NT OS/2 Emulation Subsystem. The percent complete column has the
; following meanings:
;
; XXX - Api is implemented and has passed component test
; 100 - Api is implemented and is 100% functional (i.e. passed unit test)
; 10 - Api is implemented and is 10% functional
; 0 - Api is implemented but does nothing (i.e. a stub to link against)
; blank - Api is not callable

Work Items:
1. Implement NLS support (5 days)
This work item includes the following items:
o spec the source file format for all the NLS information. This
will be a superset of the contents of COUNTRY.SYS. Currently
OS/2 uses an incomprehensible 4000 line assembler file with lots
of macros and a few includes just to keep you guessing.
o spec the binary file format of the NLS information. The NLS file(s?)
will be mapped into readonly memory at runtime and accessed directly.
o write a utility to convert the source file format to the binary file
format.
o write a throw away utility to convert COUNTRY.SYS to the new source
format.
o modify the following NLS API calls to access the new binary file format
by mapping the NLS binary file(s?). Maintain a cache so we only map
the NLS file(s?) the first time they are needed in a process.
DosSetProcessCp DosQueryCp DosQueryCtryInfo
DosQueryDBCSEnv DosQueryCollate DosMapCase
2. Implement DBCS support (5 days)
This work item includes the following items:
o implement DBCS runtime code for moving forwards and backwards through
a string (both ASCIZ and counted STRING types). Also fetching for
characters as well. How does executive access DBCS NLS information if
we are mapping it in user mode. Is it also mapped in executive space,
and if so, then that is aliasing within the same addres space.
o Modify all OS/2 API calls the parse string parameters so that they call
runtime routines to advance a string pointer and fetch characters.
These include:
DosGetMessage DosInsertMessage DosPutMessage
DosQueryMessageCP DosMapCase DosScanEnv
DosSearchPath DosExecPgm DosCreateEventSem
DosOpenEventSem DosCreateMutexSem DosOpenMutexSem
DosCreateMuxWaitSem DosOpenMuxWaitSem
DosAllocSharedMem DosGetNamedSharedMem DosLoadModule
DosQueryProcAddr DosQueryModuleHandle DosQueryAppType
DosOpen DosFindFirst DosFindNext DosSetCurrentDir
DosDelete DosEditName DosQueryPathInfo

DosCopy DosFSAttach DosQueryFSAttach DosSetFSInfo
DosQueryFSInfo DosStartSession DosCallNPipe
DosCreateNPipe DosRawReadNPipe DosRawWriteNPipe
DosWaitNPipe DosCreateQueue DosOpenQueue
3. Implement Cruiser Named Pipes (10 days)
4. DosDevioctl
We need to decide among the following options:
o remove from cruiser 32-bit API set and redefine API in
OS/2 subsystem to look like NtDeviceIoControl
o choose a subset of DosDevioctl function/category combinations
to support in subsystem (map to corresponding
NtDeviceIoControl functions)
The first option makes more sense since the 16-bit interface is available
in cruiser and the 32-bit API provides no additional functionality.
Using the NT interface is cleaner/more extendible.
5. DosFsAttach/DosQFsAttach/DosFsctl
These are fully designed. We need to decide whether these should exist as
32-bit API in cruiser since they provide no new functionality and we might
want to modify the interface in NT. We also need to decide whether these
are worth including in NT since they have no use at this time.
