radcli_avp_concat_str_by_num(3)                          Radius client library

NAME
       radcli_avp_concat_str_by_num - Look up an attribute by legacy numeric
       ID and concatenate every occurrence into a bounded buffer.

SYNOPSIS
       #include <radcli/>

       int radcli_avp_concat_str_by_num(
           char                   *buf,
           size_t                  buflen,
           const radcli_avp_list  *list,
           const radcli_ctx       *ctx,
           uint32_t                attrid,
           uint32_t                vendor,
           const char             *sep
       );

DESCRIPTION
       The _by_num() wrapper for radcli_avp_concat_str(): equivalent to
       radcli_avp_concat_str(buf, buflen, l, radcli_dict_lookup_num(ctx,
       attrid,

       vendor), sep), except that an unresolvable attribute ID is not itself a
       failure here  it is treated the same as "no occurrence present" (buf
       set to an empty string, 0 returned), matching this function's legacy-ID
       convenience role: a caller passing a well-known PW_* constant should
       not have to separately handle "not in this dictionary" as an error
       case, the same way rc_aaa()'s msg never failed just because a reply had
       no Reply-Message.

PARAMETERS
       buf    destination buffer, or NULL to only compute the needed size; see
              radcli_avp_concat_str().


       buflen size of buf, in bytes; may be 0.


       list   the list to search.


       ctx    a context with a dictionary loaded.


       attrid the attribute ID (a PW_* constant, or a vendor type ID when
              vendor is non-zero).


       vendor the vendor PEN, or 0 for a standard attribute.


       sep    separator inserted between occurrences; NULL or "" for none.


RETURN VALUE
       the number of bytes the joined result occupies (excluding the NUL
       terminator), whether or not it fit in buf; 0 if attrid/vendor resolves
       to no attribute.
