Here's the list of newly introduced functions :
- b_data(), returning the total amount of data in the buffer (currently i+o)
- b_orig(), returning the origin of the storage area, that is, the place of
position 0.
- b_wrap(), pointer to wrapping point (currently data+size)
- b_size(), returning the size of the buffer
- b_room(), returning the amount of bytes left available
- b_full(), returning true if the buffer is full, otherwise false
- b_stop(), pointer to end of data mark (currently p+i), used to compute
distances or a stop pointer for a loop.
- b_peek(), this one will help make the transition to the new buffer model.
It returns a pointer to a position in the buffer known from an offest
relative to the beginning of the data in the buffer. Thus, we can replace
the following occurrences :
bo_ptr(b) => b_peek(b, 0);
bo_end(b) => b_peek(b, b->o);
bi_ptr(b) => b_peek(b, b->o);
bi_end(b) => b_peek(b, b->i + b->o);
b_ptr(b, ofs) => b_peek(b, b->o + ofs);
- b_head(), pointer to the beginning of data (currently bo_ptr())
- b_tail(), pointer to first free place (currently bi_ptr())
- b_next() / b_next_ofs(), pointer to the next byte, taking wrapping
into account.
- b_dist(), returning the distance between two pointers belonging to a buffer
- b_reset(), which resets the buffer
- b_space_wraps(), indicating if the free space wraps around the buffer
- b_almost_full(), indicating if 3/4 or more of the buffer are used
Some of these are provided with the unchecked variants using the "__"
prefix, or with the "_ofs" suffix indicating they return a relative
position to the buffer's origin instead of a pointer.
