_IO_DISCONNECT_INTERRUPT_PARAMETERS structure

-description

The IO_DISCONNECT_INTERRUPT_PARAMETERS structure describes the parameters when unregistering an interrupt-handling routine with IoDisconnectInterruptEx.

-struct-fields

-field Version

Specifies the particular operation to be performed by IoDisconnectInterruptEx. The value for Version depends on the value specified for Parameters->Version when IoConnectInterruptEx registered the interrupt handing routine, as shown in the following table.

IO_CONNECT_INTERRUPT_PARAMETERS Version value IO_DISCONNECT_INTERRUPT_PARAMETERS Version value
CONNECT_LINE_BASED CONNECT_LINE_BASED
CONNECT_MESSAGE_BASED The value of Version output by IoConnectInterruptEx.
CONNECT_FULLY_SPECIFIED CONNECT_FULLY_SPECIFIED

-field ConnectionContext

A pointer to the KINTERRUPT or IO_INTERRUPT_MESSAGE_INFO structure that was provided by IoConnectInterruptEx when the interrupt was connected. The value for ConnectionContext depends on the value specified for Parameters->Version when IoConnectInterruptEx registered the interrupt handling routine, as shown in the following table.

IoConnectInterruptEx Version value IoDisconnectInterruptEx ConnectionContext value
CONNECT_LINE_BASED The value stored in LineBased.InterruptObject.
CONNECT_MESSAGE_BASED The value stored in MessageBased.ConnectionContext.
CONNECT_FULLY_SPECIFIED The value stored in FullySpecified.InterruptObject.
 

To minimize casting, ConnectionContext is defined as a union. Use ConnectionContext.Generic to specify the value as a PVOID. Use ConnectionContext.InterruptObject and ConnectionContext.InterruptMessageTable to specify the value as a pointer to a KINTERRUPT or IO_INTERRUPT_MESSAGE_INFO structure.

-field ConnectionContext.Generic

A pointer to a data structure of unspecified type.

-field ConnectionContext.InterruptObject

A pointer to a KINTERRUPT structure.

-field ConnectionContext.InterruptMessageTable

A pointer to an IO_INTERRUPT_MESSAGE_INFO structure.
