GPIO_READ_PINS_MASK_PARAMETERS structure (gpioclx.h)
The GPIO_READ_PINS_MASK_PARAMETERS structure describes a read operation on a bank of general-purpose I/O (GPIO) pins.
Syntax
typedef struct _GPIO_READ_PINS_MASK_PARAMETERS {
BANK_ID BankId;
PULONG64 PinValues;
GPIO_READ_PINS_FLAGS Flags;
PVOID Reserved;
} GPIO_READ_PINS_MASK_PARAMETERS, *PGPIO_READ_PINS_MASK_PARAMETERS;
Members
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. 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.
PinValues
A 64-bit variable to which the GPIO controller driver stores the values that it reads from the GPIO pins in the bank. If N is the number of GPIO pins in this bank, the pins are numbered 0 to N–1. The value from pin number 0 is saved in bit 0 (the least significant bit) of this variable, the value from pin number 1 is saved in bit 1 of this variable, and so on.
Flags
A set of flags to control the GPIO pin read operation. If the WriteConfiguredPins flag bit is set, the GPIO controller driver can read from a GPIO pin that is configured for write operations.
Reserved
Reserved for system use.
Remarks
The ReadParameters parameter of the CLIENT_ReadGpioPinsUsingMask event callback function is a pointer to a caller-allocated GPIO_READ_PINS_MASK_PARAMETERS structure.
