eio_get_event_stream — Get stream representing a variable used in internal communications with libeio.

说明

mixed eio_get_event_stream ( void )

参数

此函数没有参数。

返回值

eio_get_event_stream() returns stream on success; otherwise, NULL

范例

Example #1 Using eio with libevent

  <?php
 function  my_eio_poll ( $fd ,  $events ,  $arg ) {
     
     if ( eio_nreqs ()) {
         eio_poll ();
    }
     
 }

function  my_res_cb ( $d ,  $r ) {
     var_dump ( $r );  var_dump ( $d );
}

 $base  =  event_base_new ();
 $event  =  event_new ();

 $fd  =  eio_get_event_stream ();
 var_dump ( $fd );

 eio_nop ( EIO_PRI_DEFAULT ,  "my_res_cb" ,  "nop data" );
 eio_mkdir ( "/tmp/abc-eio-temp" ,  0750 ,  EIO_PRI_DEFAULT ,  "my_res_cb" ,  "mkdir data" );
 


// set event flags
 event_set ( $event ,  $fd ,  EV_READ   ,  "my_eio_poll" , array( $event ,  $base ));

 // set event base 
 event_base_set ( $event ,  $base );

 // enable event
 event_add ( $event );

 // start event loop
 event_base_loop ( $base );

 
 ?>

以上例程的输出类似于：

int(3)
int(0)
string(8) "nop data"
int(0)
string(10) "mkdir data"
