warning: pointer of type ‘void *’ used in arithmetic

Question

I am writing and reading registers from a memory map, like this:

//READ
return *((volatile uint32_t *) ( map + offset ));

//WRITE
*((volatile uint32_t *) ( map          


        

Answer 1

If the use of arithmetic on void pointers is really what you want as it is made possible by GCC (see Arithmetic on void- and Function-Pointers) you can use -Wno-pointer-arith to suppress the warning.
