Function nfc_poller_start 

pub unsafe extern "C" fn nfc_poller_start(
    instance: *mut NfcPoller,
    callback: NfcGenericCallback,
    context: *mut c_void,
)

Start an NfcPoller instance.

The callback logic is protocol-specific, so it cannot be described here in detail. However, the callback return value ALWAYS determines what the poller should do next: to continue whatever it was doing prior to the callback run or to stop.

Arguments

• instance (direction in, out) - pointer to the instance to be started.
• callback (direction in) - pointer to a user-defined callback function which will receive events.
• context (direction in) - pointer to a user-specific context (will be passed to the callback).
