module Buffer : sig ... endMemory buffer
val make : Unix.file_descr -> pos:int -> shared:bool -> int -> tmake fd ~pos ~shared len maps the region of the file specified by fd, pos, and len to an mmap. If shared=true, the modifications to t is shared with other processes and written back to the file.
val null : tBuild a dummy empty mmap. get_buffer always fails.
val is_null : t -> boolval msync : t -> unitCall msync(2) to flush the changes to the mapped file

val len : t -> intThe length of the mmap in bytes
val get_char : t -> int -> charval init : int -> (int -> char) -> tOn memory map
