PS1, Line 138: ghp->data = (uint8_t *)&ctrl[3];
The compiler may make optimizations based on what
passed to the function. […]
The main point of using const is *not* to assist the
compiler in optimizations but to protect yourself from mistakes... I am telling the API
user that gprs_llc_hdr_parse() does not modify the given buffer, that's it. I would
agree with you if I were actually changing the given buffer here via a const pointer, or
were passing it to some other function which does so. What I am doing here and below is
storing an address.
