[in]callbackThe callback function called when a tag is appeared or disappeared
[in]user_dataThe user data to be passed to the callback function
Returns:
0 on success, otherwise a negative error value.

void nfc_manager_set_tag_filter ( int  filter)

Sets filter of target types.

Since :
2.3
Remarks:
Bit operator OR(|) can be used in the configure parameter (like NFC_TAG_FILTER_ISO14443A_ENABLE | NFC_TAG_FILTER_ISO14443B_ENABLE) or you may choose "NFC_TAG_ALL_ENABLE" enum value to get all result. It prevent getting tag types from RF level. If the client api does call this function, default is always NFC_TAG_ALL_ENABLE.
Parameters:
[in]filterThe filter value with bits operation nfc_tag_filter_e
