nfct_catch - catch events
h | library handler |
On error, -1 is returned and errno is set appropiately. On success, a value greater or equal to 0 is returned indicating the callback verdict: NFCT_CB_STOP, NFCT_CB_CONTINUE or NFCT_CB_STOLEN

Like nfct_query but we do not wait for the reply from ctnetlink. You can use nfct_send() and nfct_catch() to emulate nfct_query(). This is particularly useful when the socket is non-blocking.
On error, -1 is returned and errno is explicitely set. On success, 0 is returned.
