.SH "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().
.SH SYNOPSIS

.SH DESCRIPTION
.PP 
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.
.SH PARAMETERS
.TP
.B req
a request from radcli_dae_process(), not yet replied to (unless RADCLI_DAE_DUPLICATE, which may be called any number of times). 

.TP
.B ack
non-zero for an ACK, zero for a NAK  ignored if req is a RADCLI_DAE_DUPLICATE. 

.TP
.B error_cause
a radcli_error_cause value for a NAK, or 0 for a bare one  ignored if req is a RADCLI_DAE_DUPLICATE. 

.TP
.B buf
filled with the reply's bytes on success. 

.TP
.B len
buf's capacity on entry; the reply's actual length on success. 

.SH RETURN VALUE
.PP
0 on success, -1 on failure (any argument NULL, req already replied to and not a RADCLI_DAE_DUPLICATE, or buf too small).
