Field Documentation

submit

int(* KlFileIO::submit) (KlFileIO *fio, int file_fd, void *buf, size_t len, off_t offset, int sock_fd, void *udata)

Submit an async file read into buf. sock_fd is an opaque key for routing/cancellation. Returns 0 on success, -1 on error.

cancel

int(* KlFileIO::cancel) (KlFileIO *fio, int sock_fd)

Cancel pending read keyed by sock_fd. Best-effort.

tick

int(* KlFileIO::tick) (KlFileIO *fio, KlFileIOResult *out, int max)

Collect completions since last tick. Called once per event loop iteration. Returns count.

destroy

void(* KlFileIO::destroy) (KlFileIO *fio)

Free backend resources.
