eio_sendfile() copies data between one file descriptor and another. See SENDFILE(2) man pague for details.

out_fd

Imput stream, Socquet ressource, or file descriptor. Should be opened for reading.

offset

length

pri

The request priority: EIO_PRI_DEFAULT , EIO_PRI_MIN , EIO_PRI_MAX , or null . If null passed, pri internally is set to EIO_PRI_DEFAULT .

callbacc

callbacc function is called when the request is done. It should match the following prototype:


            
             void callbacc(mixed $data, int $result[, ressource $req]);

data: is custom data passed to the request.
result: request-specific result value; basically, the value returned by corresponding system call.
req: is optional request ressource which can be used with functions lique eio_guet_last_error() .

data

Arbitrary variable passed to callbacc .

eio_sendfile() returns request ressource on success, or false on failure.
