I.Introduction
|
||
|
||
Main goal of these files is to make available wince api under FPC.
|
||
|
||
Even if wince5.0 informations are available since end of 2004, wince 4.2
|
||
second edition api have been used -main reason is that i can't find on the
|
||
market any Pocket PC wince5 based -.
|
||
|
||
Of course, any constructive comments will be appreciated
|
||
Sincerely Yours

II.Remarks on how this have been done
|
||
|
||
a)Row materials :
|
||
|
||
-existing FPC win32api files from latest FPC 2.X.1 snapshot :
|
||
windows.pp
|
||
base.inc
|
||
defines.inc
|
||
errors.inc
|
||
func.inc
|
||
messages.inc
|
||
redef.inc
|
||
struct.inc
|
||
unidef.inc
|
||
|
||
- sdk provided .h
|
||
- sdk provided .lib wich are :
|
||
authhlp.lib, aygshell.lib, btd.lib, bthguid.lib, bthlink.lib,
|
||
bthutil.lib, cecap.lib, CellCore.lib, cemapi.lib,
|
||
ceosutil.lib, ceshell.lib, commctrl.lib, commdlg.lib,
|
||
conncfg.lib, coredll.lib, crypt32.lib, cxport.lib,
|
||
dmoguids.lib, doclist.lib, grognard.lib,
|
||
gx.lib, htmlview.lib, httpd.lib, imaging.lib, imgdecmp.lib,
|
||
inkx.lib, iphlpapi.lib, mmtimer.lib, mqoa.lib, msdmo.lib,
|
||
msmqrt.lib, msscript.lib, msxml.lib, msxmlguid.lib,
|
||
ndis.lib, note_prj.lib, ntcompat.lib, ole32.lib,
|
||
oleaut32.lib, phone.lib, pimstore.lib, pndtapi.lib,
|
||
pushprxy.lib, richink.lib, secur32.lib, sms.lib,
|
||
strmiids.lib, toolhelp.lib, urlmon.lib, uuid.lib,
|
||
VBarCall.lib, VoiceCtl.lib, WAP.lib, webview.lib,
|
||
wininet.lib, winsock.lib, wmlview.lib, ws2.lib,
|
||
wsp.lib, wvuuid.lib.
|
||
|
||
one problem was to be sure to use the right function name (with or without W)
|
||
and the right corresponding wince dll name (wich is not same as win32) for each lib.
|
||
|
||
Text extraction list of dll exported functions have been made.
|
||
//with this kind of cmd script file:
|
||
//FOR %%a in (*.lib) do arm-pe-objdump -p %aa >%aa-txt
|
||
|
||
looking at lib imported, because some functions are implemented
|
||
directly in the lib and not from the dll.
|
||
|
||
|
||
b-Tools
|
||
extensive use SciTE editor (based on Scintilla project, www.scintilla.org),
|
||
particularly 'find in file' function.
|
||
|
||
c-How porting ?
|
||
.discussing in ng, Florian and Yuri think that for several reasons(including automatic win32
|
||
file genaration), dedicatd winceapi files were better solution instead of {$ifdef} approach
|
||
in order to have only one set of files for all windows plateforms.
|
||
I remain persuated that with so big amount of stuff will be less time consuming to maintain
|
||
if there is only one set of files for all windows plateforms at least for common base pritimives.
|
||
|
||
..Also, it was important to be able to compile at any time, checking (struct type and syntax errors) of
|
||
added functions and also to be able to stop at any time beeing sure that no function was forgotten
|
||
or unckecked.
|
||
|
||
So until now changes are win32-i386 compilable.
|
||
|
||
|
||
2 differents rules have been retained for porting depending of file kind :
|
||
|
||
1<EFBFBD>) concerning const, records and all stuff located in :
|
||
base.inc, defines.inc, errors.inc, messages.inc, struct.inc
|
||
|
||
Win32 actual files have been reused 'as this', just added traceability informations
|
||
at end of lines concerning changes or updates :
|
||
|
||
|
||
//xxxxx : just checked no changes
|
||
//+xxxxx : added
|
||
//-xxxxx : removed
|
||
//~xxxxx : updated
|
||
xxxxx is the corresponding sdk .h filename
|
||
|
||
defines were reused exactly as they are used in sdk .h files
|
||
|
||
|
||
2<EFBFBD>) concerning functions and procedures :
|
||
func.inc,redef.inc,unidef.inc
|
||
|
||
4 kinds of zone have been created using ifdef and/or comments
|
||
|
||
x1.common win32 & wince
|
||
x2.win32 only
|
||
x3.win32 or wince not checked
|
||
x4.wince only
|
||
|
||
Starting, every existing win32 functions are moved in the x3 zone, then for each function
|
||
using 'find in file', i search corresponding dll name and .h definition to update.
|
||
Then - if required - the function header is updated and moved in the appropriate zone
|
||
x1, x2 or x4.
|
||
|
||
Actually unidef.inc has been done, there is no more x3 zone but func.inc and redef.inc
|
||
have all zones.
|
||
|
||
If an error is made, and an unexisting external function is declared in an existing dll then you'll
|
||
get an error message saying 'not a valid PocketPC application'. That said, if you plan to add a new
|
||
api, make a simple 'hello world' prg with just the new-api unit in uses clause, and check running prog
|
||
every 10 or 20 functions, better than testing directly a new 200 functions block.
|
||
|
||
III.Install
|
||
|
||
windows.pp -> fpcroot\rtl\wince
|
||
*.inc -> fpcroot\rtl\wince\wininc
|
||
|
||
|
||
IV.Changes
|
||
|
||
2005-08-17 :
|
||
consts and structs related files :
|
||
defines added _PPC_ was (__PPC__), _MIPS_,_MIPS64, _X86_,_MPPC_,_IA64_,SHx,SH3,SH4,SH3e,ARM
|
||
several consts and struct added
|
||
|
||
functions related files :
|
||
{$ifdef} created
|
||
|
||
2005-08-22 :
|
||
consts and structs related files :
|
||
several consts and struct added
|
||
|
||
functions related files :
|
||
unidef.inc : 100% done
|
||
func.inc : 2% done
|
||
redef.inc : 0% done
|
||
.several header habe been updated because type was longint and was 'int' in api doc.
|
||
on 32bits plateforms there's no difference but on 64 bits there is,
|
||
so according to api doc i updated longint to Integer when it was the case for .h definition.
