in code below, explain second argument is? "constant pointer data". thanks const uint8_t *const data means function not able update either data parameter or object points . iow, can't set data point different object within function. in short: const t *p -- p writable, *p not t const *p -- same above t * const p -- *p writable, p not const t * const p -- neither p nor *p writable t const * const p -- same above edit note change data wouldn't reflected in calling function (unlike change *data ), why bother making const ? typically it's because function body needs preserve pointer throughout execution; iow, if accidentally update data you'd break later on in function. way guarantee such changes can't happen.
