Where are the constants of Nt functions?

Question

C++ / C#

Hello
Need to get information Information:

//typedef
typedef struct _IO_STATUS_BLOCK {
  union {
    NTSTATUS Status;
    PVOID    Pointer;
  } DUMMYUNIONNAME;
  ULONG_PTR Information;
} IO_STATUS_BLOCK, *PIO_STATUS_BLOCK;

switch(pStruct->Information){
    case FILE_CREATED: //Компилятор не находит константу
        .....
}

The header file "Winternl.h" is included. Where can I get these constants?

Answer 1

These constants are in the header file ntioapi.h, which should be included with wdm.h
Make sure you have the necessary #includes
