DESCRIPTION

ldns_buffer_limit()
returns the maximum size of the buffer \param[in] buffer .br 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. .br buffer: the buffer .br limit: the new limit

ldns_buffer_capacity()
returns the number of bytes the buffer can hold. .br buffer: the buffer .br 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. .br buffer: the buffer .br capacity: the capacity to use .br 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. .br buffer: the buffer .br amount: amount to use .br Returns whether this failed or succeeded

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

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

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

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