IO_PRIORITY_INFO structure

The IO_PRIORITY_INFO structure is used to hold thread priority information.

Syntax


typedef struct _IO_PRIORITY_INFO {
  ULONG            Size;
  ULONG            ThreadPriority;
  ULONG            PagePriority;
  IO_PRIORITY_HINT IoPriority;
} IO_PRIORITY_INFO, *PIO_PRIORITY_INFO;

Members

Size: Read-only member initialized by the IoInitializePriorityInfo routine.
ThreadPriority: Read-only member used to hold a thread's priority.
PagePriority: Read-only member used to hold a thread's paging priority.
IoPriority: Read-only member used to hold a thread's I/O priority.

Remarks

The IO_PRIORITY_INFO structure is used by the FltRetrieveIoPriorityInfo and FltApplyPriorityInfoThread routines to save and set a thread's priority state.

A structure of type IO_PRIORITY_INFO must be initialized before first use by calling either the IoInitializePriorityInfo routine or the FltApplyPriorityInfoThread routine.

Requirements

Version	This structure is available starting with Windows Vista.
Header	Ntifs.h (include Ntifs.h or Fltkernel.h)
