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
