ARGUMENTS

15       const unsigned char * ber
16                   BER data to decode.
17

25       asn1_get_length_der() is that this function will return a  length  even
26       if the value has indefinite encoding.
27

RETURNS

29       Return  the  decoded length value, or negative value when the value was
30       too big.
