Little-endian Byte Order

The following operations assume a little-endian byte ordering of the cstruct. If the machine-native byte ordering differs, then the get operations will reorder the bytes so that they are in machine-native byte order before returning the result, and the set operations will reorder the bytes so that they are written out in the appropriate order.

Most modern processor architectures are little-endian, so more likely than not, these operations will not do any byte reordering.

val get_uint16 : 'a rd t -> int -> uint16

get_uint16 t off returns the two bytes in t starting at offset off, interpreted as an uint16. t needs at least read capability rd.

val get_uint32 : 'a rd t -> int -> uint32

get_uint32 t off returns the four bytes in t starting at offset off. t needs at least read capability rd.

val get_uint64 : 'a rd t -> int -> uint64

get_uint64 t off returns the eight bytes in t starting at offset off. t needs at least read capability rd.

val set_uint16 : 'a wr t -> int -> uint16 -> unit

set_uint16 t off v sets the two bytes in t starting at offset off to the value v. t needs at least write capability wr.

val set_uint32 : 'a wr t -> int -> uint32 -> unit

set_uint32 t off v sets the four bytes in t starting at offset off to the value v. t needs at least write capability wr.

val set_uint64 : 'a wr t -> int -> uint64 -> unit

set_uint64 t off v sets the eight bytes in t starting at offset off to the value v. t needs at least write capability wr.
