radcli_dae_reply_to_buffer - Man Page
Produce a reply as bytes instead of sending it the L0 counterpart of radcli_dae_reply()/radcli_dae_reply_error(), for a request that came from radcli_dae_process().
Synopsis
#include <radcli/>
int radcli_dae_reply_to_buffer(
radcli_dae_request *req,
int ack,
uint32_t error_cause,
void *buf,
size_t *len
);Description
For a request radcli_dae_process() returned RADCLI_DAE_DUPLICATE for, ack and error_cause are ignored: a genuine retransmission always gets the same answer it originally got (RFC 5176 SS2.3), never a fresh one, so the bytes produced are always that cached decision's.
Parameters
- req
a request from radcli_dae_process(), not yet replied to (unless RADCLI_DAE_DUPLICATE, which may be called any number of times).
- ack
non-zero for an ACK, zero for a NAK ignored if req is a RADCLI_DAE_DUPLICATE.
- error_cause
a radcli_error_cause value for a NAK, or 0 for a bare one ignored if req is a RADCLI_DAE_DUPLICATE.
- buf
filled with the reply's bytes on success.
- len
buf's capacity on entry; the reply's actual length on success.
Return Value
0 on success, -1 on failure (any argument NULL, req already replied to and not a RADCLI_DAE_DUPLICATE, or buf too small).
