Description
It's tedious to manually prefix log messages with the file name and line number when logging errors or warnings when parsing configuration files. There should be pa_config_parser_log_error() and pa_config_parser_log_warn() that could be used by users of pa_config_parser to automatically add the file name and line number information to log messages.
