Code examples

The following code example fails the check and will give a warning:

#define no_op(X) _Generic( (X), default: X )

void example(void)
{
  int b = no_op(7);
}

The following code example passes the check and will not give a warning about this issue:

/* Compliant - has a non-default and a default association */
#define no_opP(X) ( _Generic( (X) \
  , int:     (X) \
  , default: (X) ))

void example(void)
{
  int b = no_opP(7);
}
