old_log_it.i4.v = error_uti_logging_c(log_it.i4.v)

	This routine allows the application programmer to enable or
	disable low level error messages generated by UTIs.  It can
	also be used to simply query the state of UTI error logging.

	[log_it]	UTI error logging flag
			(CLIB_DEFAULT_ARG -> return present logging flag only,
			 ERR_LOG_IT -> enable UTI generated errors to be logged,
			 ERR_NO_LOG -> disable UTI generated errors (default))

	This function returns status values as follows:

	CBS_INVARG		invalid logging flag was passed
	otherwise		previous logging state

	This function requires the following include files:

	cnsparam_h, cbslib_h, acnet_errors_h

	Related functions:

	error_init_uti, error_disp_uti, intro_error

	C/C++ usage:

	int	old_log_it;
	int	log_it = ERR_LOG_IT;

	old_log_it = error_uti_logging_c(log_it);
