radcli_avp_get_cstr_by_num(3)                            Radius client library

NAME
       radcli_avp_get_cstr_by_num - Look up an attribute by legacy numeric ID
       and read its first occurrence as a NUL-terminated string.

SYNOPSIS
       #include <radcli/>

       const char * radcli_avp_get_cstr_by_num(
           const radcli_avp_list  *list,
           const radcli_ctx       *ctx,
           uint32_t                attrid,
           uint32_t                vendor
       );

DESCRIPTION
PARAMETERS
       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.


RETURN VALUE
       a pointer valid for list's lifetime (owned by list  never freed by the
       caller), or NULL if no such attribute is defined, no occurrence exists,
       or as radcli_avp_get_cstr() (embedded NUL byte, or invalid UTF-8 for a
       RADCLI_TYPE_TEXT attribute).
