Hi, I'm trying to get the line number when a config function is called. Looking at the *fixup_dbg_pv_dump*(): " dbg_sip_msg_action = dbg_fixup_get_action(param, param_no); _dbg_sip_msg_cline = dbg_sip_msg_action->cline; " The above works as long as the config function is called with at least 1 parameter. When the config function is called with no parameters (param == NULL), this will segfault at the moment, due to invalid access at the second line. The question is, is there a straightforward way to get the config number of a config function with no parametersx? Else, I could just return a negative value meaning that the config line is unknown. Regards, Stefan
