little endian functions

val unsafe_get_uint8 : 'a carray8 -> int -> int

unsafe_get_X buf off extract integer of type X from a buffer buf starting at offset off. Unsigned types are 0 extended and signed types are sign extended to fill the ocaml type. Bounds checking is not performed. Use with caution and only when the program logic guarantees that the access is within bounds.

Note: The 31bit functions extract a 32bit integer and return it as ocaml int. On 32bit platforms this can overflow as ocaml integers are 31bit signed there. No error is reported if this occurs. Use with care. Note: The same applies to 63bit functions.

val unsafe_set_uint8 : 'a carray8 -> int -> int -> unit

unsafe_set_X buf off v stores the integer v as type X in a buffer buf starting at offset off. Bounds checking is not performed. Use with caution and only when the program logic guarantees that the access is within bounds.

Note: The 31bit functions store an ocaml int as 32bit integer. On 32bit platforms ocaml integers are 31bit signed and will be sign extended to 32bit first. Use with care. Note: The same applies to 63bit functions.
