For identify functionality, libfprint offer the functions fp_identify_finger*. These functions needs a allocated-memory list with all storage print data. However, sometimes this pre-allocation is not possible or not desirable. For example, comparisson of print datas from a database, in current state:
device = getDevice();
resultSet = findAllPrintDatasFromDatabase();
list = array();
while ( printData = resultSet.next() ) {
list.push(printData);
}
result = fp_identify_finger(device,list);
If database's print data list is too big could occur memory overflow. And need to iterate over all registers from query's result set. I want a function what permit a one-to-one comparison, how the fp_compare_print_data() below:
device = getDevice();
resultSet = findAllPrintDatasFromDatabase();
enrolledPrintData = fp_enroll_finger(device);
result = 0;
while ( printData = resultSet.next() ) {
if (result = fp_compare_print_data(enrolledPrintData,printData)) {
break;
}
}
