How to include ntddk. h

From the security focus.

Author: ilsy
If you directly include ntddk. H, you should do the following:

Namespace nt {
Extern "C "{

# Pragma warning (Disable: 4005) // macro redefinition
# Pragma warning (Disable: 4201) // nonstandard Extension
# Include <DDK/ntddk. h> // wre
# Include <tdikrnl. h>
# Pragma warning (default: 4005)
# Pragma warning (default: 4201)

Ntsysapi
Ntstatus
Ntapi
Zwquerysysteminformation (
In system_information_class systeminformationclass,
Out pvoid systeminformation,
In ulong systeminformationlength,
Out Pulong returnlength optional
);

Below are some function prototypes and other definitions

}
}
Using NT: ntstatus;

The function defined in the reference later can be used as follows:

NT: zwquerysysteminformation ()

In this way, you can include ntddk. h,

Or define a. h file for all the required definitions without ntddk. h.
