This function stops a Miniport's interrupt service routine (ISR) from being called to handle NIC interrupts.
VOID NdisMDeregisterInterrupt( IN PNDIS_MINIPORT_INTERRUPT Interrupt );
Parameters
- Interrupt
- Pointer to an interrupt object previously registered with the
NdisMRegisterInterruptfunction.
Remarks
This function releases the association between the initialized interrupt object at Interruptand the caller's MiniportISRfunction. It also releases the driver's claim on the interrupt vector or level in the registry.
This function can be called from the MiniportInitializeor the MiniportHaltfunction only if MiniportInitializepreviously made a successful call to NdisMRegisterInterrupt.
The miniport should disable its NIC from generating interrupts before it calls this function. After this function returns control, the miniport cannot call the NdisMSynchronizeWithInterruptfunction.
A driver that calls this function runs at IRQL PASSIVE_LEVEL.
Requirements
Runs on Versions Defined in Include Link to Windows CE OS 2.0 and later Ndis.h Note This API is part of the complete Windows CE OS package as provided by Microsoft. The functionality of a particular platform is determined by the original equipment manufacturer (OEM) and some devices may not support this API.
