MIFARE_APPLICATION(3) Library Functions Manual MIFARE_APPLICATION(3) NAME mifare_application_alloc, mifare_application_find, mifare_application_free, mifare_application_read, mifare_application_write -- Mifare Applications Manipulation Functions LIBRARY Mifare card manipulation library (libfreefare, -lfreefare) SYNOPSIS #include <freefare.h> MifareClassicSectorNumber * mifare_application_alloc(Mad mad, MadAid aid, size_t size); void mifare_application_free(Mad mad, MadAid aid); MifareClassicSectorNumber * mifare_application_find(Mad mad, MadAid aid); ssize_t mifare_application_read(MifareTag tag, Mad mad, MadAid aid, void *buf, size_t nbytes, MifareClassicKey key, MifareClassicKeyType key_type); ssize_t mifare_application_write(MifareTag tag, Mad mad, MadAid aid, const void *buf, size_t nbytes, MifareClassicKey key, MifareClassicKeyType key_type); DESCRIPTION The mifare_application_*() functions facilitate management of applications in a Mifare Application Directory. The mifare_application_alloc() function allocates enought sectors to store size bytes for the Application Identifier aid and returns the list of allo- cated sectors. The list of the sectors previously allocated for aid in a mad can be re- quested using mifare_application_find(). An application can be removed from a mad using mifare_application_free(). The mifare_application_read() reads at most nbytes of the application iden- tified by aid in the mad on the tag and copy them into buf. The function returns the amount of data it copied, or -1 on error. The mifare_application_write() functions writes at most nbytes of buf in the application identified by aid on the mad of the tag and returns the quantity of data written, or -1 on error. IMPLEMENTATION NOTES The mifare_application_alloc() function will try to avoid wasting space and might not allocate sectors sequentially if a large amount of space is re- quested and the target has sectors of different size. The nbytes argument of mifare_application_read() and mifare_applica- tion_write() does not need to be aligned on blocks not sectors. RETURN VALUES Unless stated otherwise, all functions return a value greater than or equal to 0 on success or -1 on failure.
