NAME
       radcli_avp_get_bytes_by_num - Look up an attribute by legacy numeric ID
       and read its first occurrence's raw bytes.

SYNOPSIS
       #include <radcli/>

       int radcli_avp_get_bytes_by_num(
           const radcli_avp_list  *list,
           const radcli_ctx       *ctx,
           uint32_t                attrid,
           uint32_t                vendor,
           const void            **out,
           size_t                 *len
       );

DESCRIPTION

       list   the list to search.


       ctx    a context with a dictionary loaded.

RETURN VALUE
       0 on success, -1 on failure (no such attribute, or no occurrence).
