DESCRIPTION

65       ldns_buffer_write_at() writes the given data to the buffer at the spec‐
66              ified position
67              buffer: the buffer
68              at: the position (in number of bytes) to write the data at
69              data: pointer to the data to write to the buffer
70              count: the number of bytes of data to write
71
