[previous] 0803 [next] [C] The '#' operator may only appear before a macro parameter.
Constraint violations REFERENCE - ISO:C90-6.8.3.2 The # Operator - Constraints

This is a constraint error

The '#' operator must always be followed by a macro parameter. Its function is to replace the parameter with a string literal by surrounding the parameter with double quotes "...".

For example: 


/*PRQA S 553,2017,3409,3410,3429 ++*/

#define S1(s) # s               /* OK */
#define S2(s) #abc = s          /* Message 0803 */
