hi,

will the currentbyteoffset field in the fileobject be updated for both
paging and non-paging i/o? or will it just be updated by non-paging i/o?

It is updated for synchronous user I/O (so not paging I/O and not
asynchronous user I/O).

Regards,

Tony

It will only be updated on NtReadFile/NtWriteFile syscalls, and only
for a file object opened for synchronous IO (no FILE_FLAG_OVERLAPPED).
