DlnGpioPinGetSupportedEventTypes() Function

The DlnGpioPinGetSupportedEventTypes() function returns all event types supported for the specified pin.

Syntax

C/C++

DLN_RESULT DlnGpioPinGetSupportedEventTypes(
    HDLN handle, 
    uint16_t pin, 
    DLN_GPIO_PIN_EVENT_TYPES* supportedEventTypes
);

Parameters

handle

A handle to the DLN-series adapter.

pin

A number of the pin for which you want to get the information.

supportedEventTypes

The pointer to the DLN_GPIO_PIN_EVENT_TYPES structure that is filled by the supported event types. After the function execution, the structure fields include the following information:


Field	Description
`count`	The number of available event types.
`eventTypes`[8]	An 8-element array. Each element corresponds to one of the supported event types.

Return Value

DLN_RES_SUCCESS (0x00): The function was successful.
DLN_RES_INVALID_PIN_NUMBER (0xAB): The pin number is not valid. Use the DlnGpioGetPinCount() function to find the maximum possible pin number.

Remarks

The DLN-1 adapters do not support GPIO events.

The DlnGpioPinGetSupportedEventTypes() function is declared in the dln_gpio.h file.
