P99_GENERIC_PCONST #define P99_GENERIC_PCONST (   PEXP,   NCONST,   CONST  ) Value: P99_GENERIC((1 ? (PEXP) : (void volatile*)1),, \ P00_VOID_QUAL_(volatile, NCONST), \ P00_VOID_QUAL_(volatile const, CONST) \ ) Generic choice based on the qualification of the target of a pointer expression. This can be used to choose a different function to call if the target of a pointer expression is const qualified or not. If we suppose that for a certain task we want to distinguish const qualified pointers and have already two functions myfunc_ and myfunc_c that handle these two cases we can simply chose like this: #define myfunc(PEXP) P99_GENERIC_PQUALIFIED((PEXP), myfunc_, myfunc_c)(PEXP) See also P99_GENERIC_PQUALIFIED P99_GENERIC_PVOLATILE P99_GENERIC_PCONSTVOLATILE P99_GENERIC_TCONST for a similar macro that works for type expressions instead of a pointer expression Remarks argument 0 maybe evaluated several times for its type but only once for its value Definition at line 1586 of file p99_generic.h.
