6、读取记录域
代码：

uint16 flen;
byte * data = null;;
// this will reset the record index to 0.
idatabase_reset (pidatabase);
// idatabase_getrecordbyid: returns a pointer to the record whose
// record id is specified.
pidbrec1 = idatabase_getrecordbyid (pidatabase, u16recid);
// get the raw data of the field
for(;;)
{
// get record 1 first field and display it
ftype = idbrecord_nextfield (pidbrec1, &fname, &flen);
data = idbrecord_getfield (pidbrec1, &fname, &ftype, &flen);
