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

       ldnsbuffersetlimit() 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

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

       ldnsbuffersetcapacity() 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

       ldnsbufferreserve() ensures BUFFER can contain at least  AMOUNT  more
              bytes.   The  buffer's  capacity is increased if necessary using
              buffersetcapacity().

              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

       ldnsbufferat()  returns  a pointer to the data at the indicated posi‐
              tion.
              buffer: the buffer
              at: position
              Returns the pointer to the data

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

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

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