DESCRIPTION

       ldns_buffer_limit()  returns  the maximum size of the buffer \param[in]
              buffer
              Returns the size

       ldns_buffer_set_limit() changes the buffer’s limit.   If  the  buffer’s
              position  is  greater  than the new limit the position is set to
              the limit.
              buffer: the buffer
              limit: the new limit

       ldns_buffer_capacity() returns the number of bytes the buffer can hold.
              buffer: the buffer
              Returns the number of bytes

       ldns_buffer_set_capacity()  changes the buffer’s capacity.  The data is
              reallocated so any pointers to the data may become invalid.  The
              buffer’s limit is set to the buffer’s new capacity.
              buffer: the buffer
              capacity: the capacity to use
              Returns whether this failed or succeeded

       ldns_buffer_reserve()  ensures  BUFFER can contain at least AMOUNT more
              bytes.  The buffer’s capacity is increased  if  necessary  using
              buffer_set_capacity().

              The  buffer’s  limit  is  always set to the (possibly increased)
              capacity.
              buffer: the buffer
              amount: amount to use
              Returns whether this failed or succeeded

       ldns_buffer_at() returns  a  pointer  to  the  data  at  the  indicated
              position.
              buffer: the buffer
              at: position
              Returns the pointer to the data

       ldns_buffer_begin()  returns  a  pointer to the beginning of the buffer
              (the data at position 0).
              buffer: the buffer
              Returns the pointer

       ldns_buffer_end() returns a pointer to the end of the buffer (the  data
              at the buffer’s limit).
              buffer: the buffer
              Returns the pointer

       ldns_buffer_current()  returns  a  pointer  to the data at the buffer’s
              current position.
              buffer: the buffer
              Returns the pointer
