type context

The type for a libaio Context.

val context : int -> context

val read : context ->
       Unix.file_descr -> int64 -> Buffer.t -> (result -> unit) -> unit

fill buffer from file at given offset and call continuation

val write : context ->
       Unix.file_descr -> int64 -> Buffer.t -> (result -> unit) -> unit

write buffer to file at given offset and call continuation

val poll : context -> Unix.file_descr -> int -> (Unix.file_descr -> unit) -> unit

poll file descriptor and call continuation

val run : context -> unit

run the context till there are no more pending requests

val process : context -> unit
