DESCRIPTION

The Fn freefare_* family of functions allow agnostic access to the Vt MifareTag present on a given NFC device.

Fn freefare_get_tags returns a NULL-terminated list of Vt MifareTag present on Vt device . This list has to be freed after usage by either:

calling the

Fn freefare_free_tags function. All tags in the list are automatically freed;

calling the

Fn freefare_free_tag function to free each tag in the list individually, and freeing the list itself using the Fn free function.

Because of the nature of the target detection process, any previously detected target will be in an inconsistent state after a call to Fn freefare_get_tags . It is the programmer's responsibility to free these targets before calling the Fn freefare_get_tags function.

Information about a given Vt MifareTag can be gathered using the Fn freefare_get_tag_type , Fn freefare_get_tag_uid and Fn freefare_get_tag_friendly_name functions.

RETURN VALUES

Unless stated otherwise, all functions return a value greater than or equal to 0 on success or -1 on failure.
