Protection QUERY Function
Parameter list not on a double word boundary.
Invalid search flags. Either the path id has not been speci­
fied, or the message id has been specified without a mes­
sage class.
An external interrupt buffer has not been declared via the
DCLBFR function, or the invoker is not in supervisor
state. When the function is invoked by CP system code,
an operation exception cannot occur because an external
interrupt buffer has not been declared.
Invalid parameter list address. The specified address is
outside the virtual machine or, for CP system code, is an
invalid real address.
Invalid parameter list address. The storage key of the spec­
ified address does not match the key of the user.
The QUERY function does not take a parameter list.
The QUERY function is used to obtain IUCV information about a virtual machine.
