C/C++
DLN_RESULT DlnGpioPinGetEventCfg(
   HDLN handle, 
   uint8_t pin, 
   uint8_t* eventType,
   uint16_t* eventPeriod
);
Parameters
handle

A handle to the DLN-series adapter.

pin

A number of the pin that you want to check.

eventType

A pointer to an unsigned 8-bit integer. After the function execution, this integer is set to the current event configuration of the pin.

eventPeriod

A pointer to an unsigned 16-bit integer. After the function execution, this integer is set to the interval at which the specified events occur.

Return Value
DLN_RES_SUCCESS (0x00)

The function retrieved the event configuration successfully.

DLN_RES_INVALID_PIN_NUMBER (0xAB)

The pin number is not valid. Use the DlnGpioGetPinCount() function to find the maximum possible pin number.
