radcli_dae_reply_to_buffer(3)                            Radius client library

NAME
       radcli_dae_reply_to_buffer - 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).
