◆ fr_radius_decode_abinary()

ssize_t fr_radius_decode_abinary	(	fr_pair_t *	vp,
		uint8_t const *	data,
		size_t	data_len
	)

Print an Ascend binary filter attribute to a string,.

Grrr... Ascend makes the server do this work, instead of doing it on the NAS.

Parameters

[in,out]	vp	Where the decoded string will be stored.
[in]	data	binary data to decodee
[in]	data_len	length of the binary data to decodee

Returns

0 OK
<0 on error. VP is untouched.

◆ fr_radius_encode_abinary()

ssize_t fr_radius_encode_abinary	(	fr_pair_t const *	vp,
		fr_dbuff_t *	dbuff
	)

Encode a string to abinary.

This routine will call routines to parse entries from an ASCII format to a binary format recognized by the Ascend boxes.

Parameters

vp	VP to encode
dbuff	where to write the VP data

Returns

>0 on success == size of the data encoded
<=0 on failure, which is the size needed to encode the data
