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
