Hi,

I have used a code which hooks ZwQueryDirectryFile in ssdt and whenever this function is called, my function, NewZwQueryDirectryFile, is executed. I need to know the full pathes of the files in the opened directory but I only get the names. Is there any way I can get the full path of the files in the direcory?
I can not use functions like GetFileNameFromHandle which are included in windows.h because I am writing a driver and including "windows.h" casues me a lot of trouble.

P.S.
I am trying to write an anti-virus.

Thank you.

Solution 1

You can try to use ZwQueryInformationFile (using FileNameInformation class) with directory handle passed to ZwQueryDirectryFile

If including Windows.h creates a problem for you, then use those functions without including Windows.h

Just call LoadLibrary and then GetProcAddress to load up the function and then call it, that'd be the simplest solution, like shown below...

C#

typedef DWORD (CALLBACK* LP_GFPNBH)(HANDLE, LPTSTR, DWORD, DWORD);
HMODULE hModule = ::LoadLibrary("Kernel32.dll");
LP_GFPNBH func = (LP_GFPNBH)::GetProcAddress(hModule, "GetFinalPathNameByHandle");

// Calling function:
func(...parameters...);
