val cstruct : ?crc:int32 -> Cstruct.t -> int32

cstruct ?crc buf computes the CRC of buf with optional initial value crc

val string : ?crc:int32 -> string -> int -> int -> int32

string ?crc buf ofs len computes the CRC of the substring of length len starting at offset ofs in string buf with optional initial value crc
