shared memory not working ?

[Mouton]

on ioftpd 4.9.4r
to use shared memory, in the initialisation, i do:

hShell32 = LoadLibrary("shell32.dll");
if ( Target && hShell32 )
{
Allocate = GetProcAddress(hShell32, "SHAllocShared");
Free = GetProcAddress(hShell32, "SHFreeShared");
Unlock = GetProcAddress(hShell32, "SHUnlockShared");
Lock = GetProcAddress(hShell32, "SHLockShared");

if ( Allocate && Free && Lock && Unlock && hTarget )
{ ... }
else {
LPVOID lpMsgBuf;
FormatMessage(
FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_FROM_SYSTEM |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
GetLastError(),
MAKELANGID(LANG_NEUTRAL, SUBLANG_DEFAULT), // Default language
(LPTSTR) &lpMsgBuf,
0,
NULL );
printf("Error on Allocate. Error: %lX - %s\n",GetLastError(),lpMsgBuf); fflush(stdout);
}
}this works ok on some pc, but on others:

Error on Allocate. Error: 7F - Kan opgegeven procedure niet vinden.

(means "Can't find the procedure that you filled in.")

Wasn't shared memory supposed to work on all WinNT kernel based OS now ..?
I get this on Win2k and some else reported this happening on WinXP SP1 too :\
While on another SP1, it works ok...

Use call by ordinal for win2k.
Shared memory works for all but it isnt defined that way for all shell32.dll versions.

Thx.

Off the record, for those who that might interest:

//Allocate = GetProcAddress(hShell32, "SHAllocShared");
Allocate = GetProcAddress(hShell32, (char *)520);
//Free = GetProcAddress(hShell32, "SHFreeShared");
Free = GetProcAddress(hShell32, (char *)523);
//Unlock = GetProcAddress(hShell32, "SHUnlockShared");
Unlock = GetProcAddress(hShell32, (char *)522);
//Lock = GetProcAddress(hShell32, "SHLockShared");
Lock = GetProcAddress(hShell32, (char *)521);
