# Bitpacking Functions

Libogg contains a basic bitpacking library that is useful for manipulating data within a buffer.

All the libogg specific functions are declared in "ogg/ogg.h".

function | purpose
oggpack_writeinit | Initializes a buffer for writing using this bitpacking library.
oggpack_writecheck | Asynchronously checks error status of bitpacker write buffer.
oggpack_reset | Clears and resets the buffer to the initial position.
oggpack_writeclear | Frees the memory used by the buffer.
oggpack_readinit | Initializes a buffer for reading using this bitpacking library.
oggpack_write | Writes bytes to the specified location within the buffer.
oggpack_look | Look at a specified number of bits, <=32, without advancing the location pointer.
oggpack_look1 | Looks at one bit without advancing the location pointer.
oggpack_adv | Advances the location pointer by a specified number of bits.
oggpack_adv1 | Advances the location pointer by one bit.
oggpack_read | Reads a specified number of bits from the buffer.
oggpack_read1 | Reads one bit from the buffer.
oggpack_bytes | Returns the total number of bytes contained within the buffer.
oggpack_bits | Returns the total number of bits contained within the buffer.
oggpack_get_buffer | Returns a pointer to the buffer encapsulated within the oggpack_buffer struct.
