Process Status API

Obtains information about processes and device drivers.

Functions

EmptyWorkingSet(HANDLE hProcess) → Win32Result<bool> psapi
Removes as many pages as possible from the working set of the specified process.
EnumDeviceDrivers(Pointer<Pointer<NativeType>> lpImageBase, int cb, Pointer<Uint32> lpcbNeeded) → Win32Result<bool> psapi
Retrieves the load address for each device driver in the system.
EnumPageFiles(Pointer<NativeFunction<PENUM_PAGE_FILE_CALLBACK>> pCallBackRoutine, Pointer<NativeType> pContext) → Win32Result<bool> psapi
Calls the callback routine for each installed pagefile in the system.
EnumProcesses(Pointer<Uint32> lpidProcess, int cb, Pointer<Uint32> lpcbNeeded) → Win32Result<bool> psapi
