call_env_parse()

static int call_env_parse ( TALLOC_CTX *  ctx, void *  out, tmpl_rules_t const *  t_rules, CONF_ITEM *  ci, call_env_ctx_t const *  cec, UNUSED call_env_parser_t const *  rule  )

static

Custom call_env parser for loading files data.

getrecv_filename()

static int getrecv_filename ( TALLOC_CTX *  ctx, char const *  filename, fr_htrie_t **  ptree, PAIR_LIST_LIST **  pdefault, fr_type_t  data_type, fr_dict_attr_t const *  key_enum, fr_dict_t const *  dict  )

Here is the caller graph for this function:

mod_files()

static unlang_action_t mod_files ( rlm_rcode_t *  p_result, module_ctx_t const *  mctx, request_t *  request  )

static

Initiate a files data lookup.

The results of call_env parsing are a structure containing the tmpl_t representing the key and the parsed files data, meaning tmpl expansion does not happen by default. First we push the tmpl onto the stack for evaluation, then the lookup is done in mod_files_resume.

mod_files_resume()

static unlang_action_t mod_files_resume ( rlm_rcode_t *  p_result, UNUSED int *  priority, request_t *  request, void *  uctx  )

static

Lookup the expanded key value in files data.
