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 position 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 buffer
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
