QA·C Help - 1029

	1029	[E] Whitespace encountered between backslash and new-line has been ignored.

Language extensions		REFERENCE - ISO:C90-5.1.1.2 Translation Phases

A backslash ('\') located as the final character in a line of code is used in the C language as a means of splicing two physical lines together into a single logical line of code. However in the ISO:C Standard this syntax is only recognised when the blackslash character immediately precedes the new-line character. If any whitespace characters are encountered between the backslash and the new-line character, the sequence will not be recognised.

This behaviour can be modified by using the -slashwhite+ language extension option which instructs QA·C to ignore any trailing whitespace characters. Message 1029 is generated to indicate that whitespace characters have been encountered and ignored.

For example:


/*PRQA S 553,2017,3429,3435,3456,3459 ++*/
/************************************
 * OPTIONS: -sl+

/* Message 1029 will be generated on the following
   statement if there are whitespace characters
   following the \ */

#define M_1904(x)          /* Message 1029 */    \
   do {                    \
         if ((x) < 200)    \
         {                 \
            (x) = (x) + 1; \
         }                 \
         else              \
         {                 \
            (x) = 200;     \
         }                 \
   } while (0)
