DESCRIPTION

ldns_buffer_write_at() writes the given data to the buffer at the specified position buffer: the buffer at: the position (in number of bytes) to write the data at data: pointer to the data to write to the buffer count: the number of bytes of data to write ldns_buffer_write() writes count bytes of data to the current position of the buffer buffer: the buffer data: the data to write count: the length of the data to write ldns_buffer_write_string_at() copies the given (null-delimited) string to the specified position at the buffer buffer: the buffer at: the position in the buffer str: the string to write ldns_buffer_write_string() copies the given (null-delimited) string to the current posi‐ tion at the buffer buffer: the buffer str: the string to write ldns_buffer_write_u8_at() writes the given byte of data at the given position in the buf‐ fer buffer: the buffer at: the position in the buffer data: the 8 bits to write ldns_buffer_write_u8() writes the given byte of data at the current position in the buffer buffer: the buffer data: the 8 bits to write ldns_buffer_write_u16_at() writes the given 2 byte integer at the given position in the buffer buffer: the buffer at: the position in the buffer data: the 16 bits to write ldns_buffer_write_u16() writes the given 2 byte integer at the current position in the buffer buffer: the buffer data: the 16 bits to write ldns_buffer_read_at() copies count bytes of data at the given position to the given data- array buffer: the buffer at: the position in the buffer to start data: buffer to copy to count: the length of the data to copy ldns_buffer_read() copies count bytes of data at the current position to the given data- array buffer: the buffer data: buffer to copy to count: the length of the data to copy ldns_buffer_read_u8_at() returns the byte value at the given position in the buffer buffer: the buffer at: the position in the buffer Returns 1 byte integer ldns_buffer_read_u8() returns the byte value at the current position in the buffer buffer: the buffer Returns 1 byte integer ldns_buffer_read_u16_at() returns the 2-byte integer value at the given position in the buffer buffer: the buffer at: position in the buffer Returns 2 byte integer ldns_buffer_read_u16() returns the 2-byte integer value at the current position in the buffer buffer: the buffer Returns 2 byte integer ldns_buffer_read_u32_at() returns the 4-byte integer value at the given position in the buffer buffer: the buffer at: position in the buffer Returns 4 byte integer ldns_buffer_read_u32() returns the 4-byte integer value at the current position in the buffer buffer: the buffer Returns 4 byte integer ldns_buffer_write_u32() writes the given 4 byte integer at the current position in the buffer buffer: the buffer data: the 32 bits to write ldns_buffer_write_u32_at() writes the given 4 byte integer at the given position in the buffer buffer: the buffer at: the position in the buffer data: the 32 bits to write
