[ace-users] ACE UDP using ACE_Asynch_Write_Dgram

[Steve Huston]

Please use the PROBLEM-REPORT-FORM whenever asking questions on this
list.

The class names would indicate that you're using an added AIO facility
that's not supported as part of ACE. Please contact the provider for
support.

If that organization can't help you, please feel free to contact me to
discuss options for supporting your application.

Best regards,
-Steve
