print (defined('MSG_DONTWAIT') ? 'defined:'.constant('MSG_DONTWAIT') : 'not defined');

just a typo fix in the example, missed the ', it's a bug just a typo in my example.

AFAICT, this is not really a bug since that constant has never existed. I guess Arnaud is going to add it..:)

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at
http://snaps.php.net/.
 
Thank you for the report, and for helping us make PHP better.

Added MSG_DONTWAIT constant in HEAD (php6), it will be defined if the system provides it.
stream_set_blocking() should be used if not.

To be documented: MSG_DONTWAIT added in PHP 6.

just a workaround, defining it manually or passing 0x40 directly will solve the problem till the release.

 [2009-05-20 09:09 UTC] lbarnaud@php.net

Added to 5.2/5.3.

To be documented: Since PHP 5.2.10; If system supports it.

On Windows Systems it still don't work. I use PHP 5.3 and I can't work really well so. I've hard problems because of that.
Is there any solution?

If I use the Testcode above ( print (defined('MSG_DONTWAIT') ? 'defined:'.constant('MSG_DONTWAIT') : 'not defined'); ) it prints not defined.

<?php

 function workaround() {
  if (!defined('MSG_DONTWAIT')) {
   define('MSG_DONTWAIT', 0x40);
   return 1;
  }
 }
 workaround();

?>

workaround... return 1 if it was used... maybe useful for some kinda debug... also the Compat Project

Apparently, it has been forgotten to close this.
