Detailed Description

This file contains API for libeio fiber wrappers.

Wrapper functions are not documented as they clone the libeio prototypes and their documenting would result in useless copy'n'paste here. libeio documentation can be used as a reference on this functions. The only difference is that first argument in the wrappers is always fiber context, and eio_cb and data pointer are passed internally, and so are not present in the prototypes.

Definition in file eio.h.

Function Documentation

void fbr_eio_init

(

)

Initialization routine for libeio fiber wrapper.

This functions initializes libeio and sets up the necessary glue code to interact with libev (and in turn libevfibers).

Must be called only once, uses EV_DEFAULT event loop internally, but any fiber scheduler can interact with libeio independently.

fbr_ev_eio

fbr_ev_wait

void fbr_ev_eio_init	(	FBR_P_ struct fbr_ev_eio *	ev,
		eio_req *	req
	)

Initializer for eio event.

This functions properly initializes fbr_ev_eio struct. You should not do it manually.
