[previous] 3664 [next] [E] Using a dot operator to access an individual bit is a language extension.
Language extensions

A dot operator ('.'), is being used in a non-standard way. Some compilers permit individual bits of an object to be addressed using the character "." as a special operator.

The objects in question will have been defined using non-standard data types which QAC does not support directly. However such code can usually be parsed by redefining the data type to a standard integral type (using a configuration macro),

For example: 


/*PRQA S 2017,3408,3447 ++*/

extern unsigned int a;

extern void foo(void)
{
    a.1 = 0u;                           /* Message 3664 */
}
