int ber_declen (const char *buf, int *len, int max)

Detailed Description

Implements BER length octet encoding and decoding.

This source file implements BER encoding and decoding of the length octets.

Definition in file ber_len.c.

Function Documentation

◆ ber_declen()

int ber_declen ( const char *  buf,
int *  len,
int  max 

ber_declen: Decode BER length octets. Returns

0 : number of bytes read

-1 : not enough room to read bytes within max bytes -2 : other error

After return: len = -1 indefinite length. len >= 0 definite length

◆ ber_enclen()

int ber_enclen ( ODR  o,
int  len,
int  lenlen,
int  exact 

ber_enclen: Encode BER length octets. If exact, lenlen is the exact desired encoding size, else, lenlen is the max available space. Len < 0 = Indefinite encoding. Returns: >0 success, number of bytes encoded. Returns: =0 success, indefinite start-marker set. 1 byte encoded. Returns: -1 failure, out of bounds.
