DESCRIPTION

ldns_buffer_write_at(): writes the given data to the buffer at the specified position .br buffer: the buffer .br at: the position (in number of bytes) to write the data at .br data: pointer to the data to write to the buffer .br count: the number of bytes of data to write

ldns_buffer_write(): writes count bytes of data to the current position of the buffer .br buffer: the buffer .br data: the data to write .br count: the length of the data to write

ldns_buffer_write_string_at(): copies the given (nul-delimited) string to the specified position at the buffer .br buffer: the buffer .br at: the position in the buffer .br str: the string to write

ldns_buffer_write_string(): copies the given (nul-delimited) string to the current position at the buffer .br buffer: the buffer .br str: the string to write

ldns_buffer_write_u8_at(): writes the given byte of data at the given position in the buffer .br buffer: the buffer .br at: the position in the buffer .br data: the 8 bits to write

ldns_buffer_write_u8(): writes the given byte of data at the current position in the buffer .br buffer: the buffer .br data: the 8 bits to write

ldns_buffer_write_u16_at(): writes the given 2 byte integer at the given position in the buffer .br buffer: the buffer .br at: the position in the buffer .br data: the 16 bits to write

ldns_buffer_write_u16(): writes the given 2 byte integer at the current position in the buffer .br buffer: the buffer .br data: the 16 bits to write

ldns_buffer_read_at(): copies count bytes of data at the given position to the given dat-array .br buffer: the buffer .br at: the position in the buffer to start .br data: buffer to copy to .br count: the length of the data to copy

ldns_buffer_read(): copies count bytes of data at the current position to the given dat-array .br buffer: the buffer .br data: buffer to copy to .br count: the length of the data to copy
