NTOSKRNL.NtQuerySystemInformation() and NTOSKRNL.NtSetSystemInformation(). --- Partially implemented (kernel32/process/proc.c) KERNEL32.GetPriorityClass(), KERNEL32.SetPriorityClass() and NTDLL.CsrSetPriorityClass() (stub only). Renamed (in include/csrss/csrss.h) priority class macros: #define CSR_PRIORITY_CLASS_NORMAL (0x10) #define CSR_PRIORITY_CLASS_IDLE (0x20) #define CSR_PRIORITY_CLASS_HIGH (0x40) #define CSR_PRIORITY_CLASS_REALTIME (0x80) --- Implemented (kernel32/misc/error.c) #include <kernel32/error.h> DWORD STDCALL SetLastErrorByStatus ( NTSTATUS Status ); to replace SetLastError(RtlNtStatusToDosError(Status)) in KERNEL32, and fixed KERNEL32.SetLastError() KERNEL32.GetLastError() to use the field in NT_TEB (LastError is per thread not per process). --- Implemented (lib/kernel32/sysinfo.c) GetSystemInfo() (to be completed). --- Fixed rosapps/sysutils/makefile to use ROS import libraries. --- Added QSI to the system utilities set. The target is writing a tool that can be used to query as much system information as possible from user mode (to be finished and tested only under nt4sp4/x86; it was NOT tested under ROS: it crashes immediately and needs NtQuerySystemInformation implemented!). svn path=/trunk/; revision=1137
