/* How to use:
|
||
|
|
History got us another time. If you want to write a module
|
||
|
|
that uses either native-api or os2-services...no problem.
|
||
|
|
But if you want to use both of them you run into type conflicts.
|
||
|
|
BOOL is not very surprising. But there are many other types
|
||
|
|
whose names are equal. This results from the fact that NT
|
||
|
|
should originally become OS/2 3.0.
|
||
|
|
So your solution lies in including this file instead of os2.h
|
||
|
|
and ntddk.h. What this file here does is, it puts the os2-types+
|
||
|
|
functions into the namespace OS2 while the nt-types+functions are
|
||
|
|
put into the namespace NT. The still conflicting #defines are handled
|
||
|
|
like this: If ntddk.h defintes a symbol FOO and os2.h does the same,
|
||
|
|
this file here undefines the ntddk.h-one and renames it to NT_FOO.
|
||
|
|
This is only done for conflicting symbols. Of course, this ist a
|
||
|
|
source for errors. But is there a better solution than renaming
|
||
|
|
all of the symbols?
