GPIO_CLX_ReleaseInterruptLock function (gpioclx.h)

  • Article

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

Syntax

void GPIO_CLX_ReleaseInterruptLock(
  [in] PVOID   Context,
  [in] BANK_ID BankId
);

Parameters

[in] Context

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.

[in] BankId

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.

Return value

None

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.

Requirements

Requirement Value
Minimum supported client Available starting with Windows 8.
Target Platform Universal
Header gpioclx.h
Library Msgpioclxstub.lib
IRQL See Remarks.
