[previous] 0168 [next] [U] Unknown length modifier used with 'E' conversion specifier, number %s.
Explicitly undefined REFERENCE - ISO:C90-7.9.6.1 Formatted input/output functions

An unknown length modifier is being used in conjunction with a '%E' conversion specifier in a printf format string.

The only valid length modifier for a '%E' conversion specifier is "L" - indicating that the corresponding argument is of type long double.

In the code example below "l" has been used; but "l" is only valid with integer conversion specifiers.

#include <stdio.h>

    printf("The total is %LE", ltot);  /* OK */

    printf("The total is %lE", ftot);  /* Message 0168 */
