_Requires_lock_held_ ( Number )

_Must_inspect_result_ _Success_ ( return! = 0 )

Returns the name of an atom.

MSDN: GetRegionData, Return Values:

"If the function succeeds and dwCount specifies an adequate number of bytes, the return value is always dwCount. If dwCount is too small or the function fails, the return value is 0. If lpRgnData is NULL, the return value is the required number of bytes.

If the function fails, the return value is zero."

Parameters

atom	- The atom to be queried.
pustrName	- Pointer to an initialized UNICODE_STRING that receives the name of the atom. The function does not update the Length member. The string is always NULL-terminated.

Returns: The length of the name in characters, or 0 if the function fails.

Note: The function does not aquire any global lock, since synchronisation is handled by the RtlAtom function.
