Re: GetCurrentProcessId import prblem

Both these functions are defined as inline in the SDK. Current process ID
and current process handle are pseudo id and pseudo handle:

_inline HANDLE GetCurrentProcess(void) {
return ((HANDLE)(SH_CURPROC+SYS_HANDLE_BASE));
}

_inline DWORD GetCurrentThreadId(void) {
return ((DWORD)(((HANDLE *)(PUserKData+SYSHANDLE_OFFSET))[SH_CURTHREAD]));
}

_inline DWORD GetCurrentProcessId(void) {
return ((DWORD)(((HANDLE *)(PUserKData+SYSHANDLE_OFFSET))[SH_CURPROC]));

I've put together a sample that shows how to access this information on PPC:

Alex,

I have tried to use your sample, but have some problems: I get an id,
but
this is a negative number. I use the ID in SetWindowsHookEx, which
fails with a NotSupportedException, and I don't know, if this has
something to do with the ID.

The function for getting the current thread id:

static int GetCurrentThreadID()
{
uint PUserKData = GetCPUArchitecture()
==PROCESSOR_ARCHITECTURE.PROCESSOR_ARCHITECTURE_ARM?
PUserKDataARM:PUserKDataX86;
IntPtr pBase = new IntPtr((int) (PUserKData + SYSHANDLE_OFFSET));
return Marshal.ReadInt32(pBase, SH_CURPROC * 4);
}

PUserKDataARM = 0xFFFFC800, SYSHANDLE_OFFSET = i think 4 in my case.
This is uint. Converting it to int results in a negative number, is
that correct?
Thanks,
Tibor
