It's not a type of char* but const char*.

Client are not supposed to deallocate memory pointed by const char*
returned from those functions above. They are deallocated in OGRLayer
destructor, more precisely, in destructors of layer classes derived from
OGRLayer in particular driver.

Also, you're reading those values in read-only mode.
