How "IRP_MJ_CLOSE" come out when i call "ReadFile"

Harvey

HI, everbody:
I have wrote a filter file system driver to print all the IRP sent to a certain disk, when i call the WinAPI "ReadFile" in user mode, i catch "IRP_MJ_CLOSE" and then "IRP_MJ_READ", when i call "CloseHandle", i catch "IRP_MJ_CLEANUP", the question is that how do "IRP_MJ_CLOSE" come out when i call "ReadFile" ?

From the WDK documentation for IRP_MJ_CLEANUP:

"Receipt of the IRP_MJ_CLEANUP request indicates that the *handle*
reference count on a file object has reached zero."

From the WDK documentation for IRP_MJ_CLOSE:

"Receipt of the IRP_MJ_CLOSE request indicates that the reference
count on a file object has reached zero."

Is the difference abvoe between "handle reference count" and
"reference count" meaningful? If so, what does that mean?
