DESCRIPTION

41       ldns_buffer_limit() returns the maximum size of the buffer
42
43       ldns_buffer_set_limit()  changes  the  buffer's limit.  If the buffer's
44              position is greater than the new limit the position  is  set  to
45              the limit.
46
47       ldns_buffer_capacity() returns the number of bytes the buffer can hold.
48
49       ldns_buffer_set_capacity()  changes the buffer's capacity.  The data is
50              reallocated so any pointers to the data may become invalid.  The
51              buffer's limit is set to the buffer's new capacity.
52
53       ldns_buffer_reserve()  ensures  BUFFER can contain at least AMOUNT more
54              bytes.  The buffer's capacity is increased  if  necessary  using
55              buffer_set_capacity().
56
57              The  buffer's  limit  is  always set to the (possibly increased)
58              capacity.
59
60       ldns_buffer_at() returns a pointer to the data at the  indicated  posi‐
61              tion.
62
63       ldns_buffer_begin()  returns  a  pointer to the beginning of the buffer
64              (the data at position 0).
65
66       ldns_buffer_end() returns a pointer to the end of the buffer (the  data
67              at the buffer's limit).
68
69       ldns_buffer_current()  returns  a  pointer  to the data at the buffer's
70              current position.
