◆ _Success_()

_Must_inspect_result_ _Success_ ( return ! = 0 )

Returns the name of an atom.

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.
