eio_poll — Can be to be called whenever there are pending requests that need finishing.
eio_poll() can be used to implement special event loop. For this eio_nreqs() could be used to test if there are unprocessed requests.
Note:
Applicable only when implementing userspace event loop.
此函数没有参数。
If any request invocation returns a non-zero value, returns that value.
Otherwise, it returns 0
.
Example #1 eio_poll() example
<?php
function res_cb ( $data , $result ) {
var_dump ( $data );
var_dump ( $result );
}
eio_nop ( EIO_PRI_DEFAULT , "res_cb" , "1" );
eio_nop ( EIO_PRI_DEFAULT , "res_cb" , "2" );
eio_nop ( EIO_PRI_DEFAULT , "res_cb" , "3" );
while ( eio_nreqs ()) {
// Some specific IPC or so
eio_poll ();
}
?>
以上例程的输出类似于:
string(1) "1" int(0) string(1) "3" int(0) string(1) "2" int(0)
