ACE_POSIX_AIOCB_Proactor(3)

NAME

ACE_POSIX_AIOCB_Proactor -

This Proactor makes use of Asynchronous I/O Control Blocks (AIOCB) to notify/get the completion status of the aio_ operations issued.

DESCRIPTION

Methods used to create Asynch_IO objects. We create the right

objects here in these methods.
