Callback problem

Question

Hi , I run the code below and receive the following errors:
typedef VOID ( CALLBACK * mPCH341_INT_ROUTINE ) ( // ÖжϷþÎñ³ÌÐò
ULONG iStatus );
Errors:
1-function returning function is not allowed
2-expected a ')'
3-Identifier "ULONG" is undefined
4-Identifier "mPCH341_INT_ROUTINE" is undefined

Answer 1

Try adding #include <Windows.h> to the beginning of your file.

Answer 2

My error with four mentioned errors was fixed. Now I have two new errors with following command line:
typedef VOID(CALLBACK* mPCH341_NOTIFY_ROUTINE)(ULONG iEventStatus);
Errors are:
1-'NTSTATUS' :redefinition different basic types
2-'left-side modifier':cannot modify pointers to data
