unsafe_get_X str off extract integer of type X from string str 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.

get_X str off same as unsafe_get_X but with bounds checking.

unsafe_set_X str off v stores the integer v as type X in string str 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.

set_X str off v same as unsafe_set_X but with bounds checking.
