NtDeleteFile usage

I'm wondering how can I use NtDeleteFile to delete C:\file.txt
It's being called from a Native Application, and the actual return code is something like -10279875....
lpPathName = "\\??\\C:\\file.txt"

Win XP SP2 + WDK 2008

PathNameString.Length = 19;
   PathNameString.Buffer = (WCHAR *)lpPathName;
   PathNameString.MaximumLength = PathNameString.Length+sizeof(WCHAR);
   
   ObjectAttributes.Length = sizeof(OBJECT_ATTRIBUTES);
   ObjectAttributes.RootDirectory = NULL;
   ObjectAttributes.ObjectName = &PathNameString;
   ObjectAttributes.Attributes = OBJ_CASE_INSENSITIVE| OBJ_INHERIT;
   ObjectAttributes.SecurityDescriptor = NULL;
   ObjectAttributes.SecurityQualityOfService = NULL;
   
   errCode = NtDeleteFile(&ObjectAttributes);

Is this being run locally - i.e. not over the network?
These types of errors are normally down to network access-related issues...

Please ignore my comment.
This is more of jkr's field than mine...

That just works =)
Thank you very much.

BTW, you can simplify that and make it more error proof using

UNICODE_STRING PathNameString;
OBJECT_ATTRIBUTES ObjectAttributes;
 
RtlCreateUnicodeString(&PathNameString,lpPathName);
 
InitializeObjectAttributes( &ObjectAttributes, &PathNameString, OBJ_CASE_INSENSITIVE, NULL, NULL );
 
errCode = NtDeleteFile(&ObjectAttributes);
