The required implementation would actually be:
if (param->file_name == NULL)
ret = -EINVAL;
else
ret = 0;
The TM parameter file_name is used by function app_config_parse_tm() in file config_parse_tm.c.
Regarding the way the error management (including the error messages) is done in our parser (currently done by repeatedly setting the ret variable), I would like to improve (replace) when I get the time to take another look at this.
