- REFERENCE_BY_POINTER (18)
- Arguments:
- Arg1: 0000000000000000, Object type of the object whose reference count is being lowered
- Arg2: ffffe48024426080, Object whose reference count is being lowered
- Arg3: 0000000000000010, Reserved
- Arg4: 0000000000000001, Reserved
- The reference count of an object is illegal for the current state of the object.
- Each time a driver uses a pointer to an object the driver calls a kernel routine
- to increment the reference count of the object. When the driver is done with the
- pointer the driver calls another kernel routine to decrement the reference count.
- Drivers must match calls to the increment and decrement routines. This BugCheck
- can occur because an object's reference count goes to zero while there are still
- open handles to the object, in which case the fourth parameter indicates the number
- of opened handles. It may also occur when the object's reference count drops below zero
- whether or not there are open handles to the object, and in that case the fourth parameter
- contains the actual value of the pointer references count.

- REFERENCE_BY_POINTER (18)
- Arguments:
- Arg1: 0000000000000000, Object type of the object whose reference count is being lowered
- Arg2: ffffe48024426080, Object whose reference count is being lowered
- Arg3: 0000000000000010, Reserved
- Arg4: 0000000000000001, Reserved
- The reference count of an object is illegal for the current state of the object.
- Each time a driver uses a pointer to an object the driver calls a kernel routine
- to increment the reference count of the object. When the driver is done with the
- pointer the driver calls another kernel routine to decrement the reference count.
- Drivers must match calls to the increment and decrement routines. This BugCheck
- can occur because an object's reference count goes to zero while there are still
- open handles to the object, in which case the fourth parameter indicates the number
- of opened handles. It may also occur when the object's reference count drops below zero
- whether or not there are open handles to the object, and in that case the fourth parameter
- contains the actual value of the pointer references count.
