int mtk_os_hal_gpioif_int_callback_register ( gpioif_group  group,
gpioif_int_callback  callback,
void *  user_data 
)

This function is used to register user's interrupt callback.

It's used for GPIOIF interrupt function handle.
User can register a callback function when using GPIOIF interrupt.
When one interrupt is triggered and a related user callback is called in OS-HAL interrupt handle function which we register.
This typedef is used to describe the callback function what the user wants to call.

Parameters
[in]ctlr: GPIOIF controller used with the device.
[in]callback: The callback function given by test layer. which will be called before we set gpioif related setting.
[in]user_data: A parameter given by OS-HAL and will be passed to user when the callback function is called.
Returns
Return "0" if callback register successfully.
Return -GPIOIF_EINVAL if ctlr or callback or user_data is NULL.
