GPIO_QUERY_ENABLED_INTERRUPTS_PARAMETERS structure (gpioclx.h)

The GPIO_QUERY_ENABLED_INTERRUPTS_PARAMETERS structure indicates which interrupt pins in a bank of general-purpose I/O (GPIO) pins are enabled.

Syntax

typedef struct _GPIO_QUERY_ENABLED_INTERRUPTS_PARAMETERS {
  BANK_ID BankId;
  ULONG64 EnabledMask;
} GPIO_QUERY_ENABLED_INTERRUPTS_PARAMETERS, *PGPIO_QUERY_ENABLED_INTERRUPTS_PARAMETERS;

Members

BankId

The identifier for the bank of GPIO pins to query for enabled interrupts. If N is the number of banks in the GPIO controller, BankId is an integer in the range 0 to N–1. The GPIO framework extension (GpioClx) previously obtained the number of banks in the controller from the CLIENT_QueryControllerBasicInformation event callback function. For more information, see Remarks in CLIENT_CONTROLLER_BASIC_INFORMATION.

EnabledMask

A 64-bit mask that indicates which interrupts are enabled in the specified bank. A bit in the mask that is set to 1 identifies an interrupt pin that is enabled for interrupts. All other bits in the mask are 0. If N is the number of pins in this bank, the pins are numbered 0 to N–1. Bit 0 (the least significant bit) in the mask represents pin 0, bit 1 represents pin 1, and so on.

Remarks

The QueryEnabledParameters parameter of the CLIENT_QueryEnabledInterrupts event callback function is a pointer to a caller-allocated GPIO_QUERY_ENABLED_INTERRUPTS_PARAMETERS structure. Before calling this function, the caller writes a bank ID to the BankId member of this structure to specify which bank of GPIO pins to query. The function writes a mask value to the EnabledMask member of this structure to indicate which interrupts are enabled in the specified bank.
