Know if const qualifier is used

Question

Not in standard C, i.e. not portably.

myString is just a char* in foo, all other information is lost. Whatever you feed into the function is automatically converted to char*.

And C does not know about ".rodata".

Depending on your platform you could check the address in myString (if you know your address ranges).
