GPIO_CLX_ReleaseInterruptLock function

Description

The GPIO_CLX_ReleaseInterruptLock method releases an interrupt lock on the specified bank.

Parameters

Context [in]

A pointer to the GPIO controller driver's device context. The GPIO framework extension (GpioClx) passes this pointer value as a parameter to the callback functions that are implemented by the GPIO controller driver.

BankId [in]

The identifier for this bank of GPIO pins. If N is the number of banks in the GPIO controller, BankId is an integer in the range 0 to N–1.

Remarks

This method releases the interrupt lock that the caller acquired in a previous call to the GPIO_CLX_AcquireInterruptLock method.

If the previous call to the GPIO_CLX_AcquireInterruptLock method raised the calling thread's IRQL, GPIO_CLX_ReleaseInterruptLock restores this IRQL to its original level.

If the Context parameter is NULL or points to an invalid GPIO device context, this method causes a bug check in debug builds of GpioClx.
