char* getString(cdbfapiPlus* handle, int fieldno);

The function getString() returns content of any field as a string value or NULL.
If a field is a binary memo, you need another function: getMemoBuf().
Do not forget to call readRecord().

{
    // your code
    readRecord( dbf, row );
    printf( "%s\n", getString( dbf, 0 ) );
    // your code
}
