How about:
struct buf_t {
char *first ;
char *cur ;
char *last ;
size_t size ;
size_t remaining ;
} ;
/* implement various buf-management macros */
Implement some or all, as needed. Replace the char* elements
with a union of various ptr types if desired. Keep the type
definition available; there's no need for an opaque struct.
Now write programs to toss around buf_t* instead of char*. It's
not that difficult.
