I am just about to find out how I could make use of the asio library, and am wondering if async io also can be done without using handler functions.
I recognize that it is possible to use it in a blocked manner as follows:
assuming we have an open socket: sock
read(sock, buf); ... use the buffer contents ...
Now I am wondering if I could also accomplish something like:
cp = async_read(sock, buf); ... do something useful ... cp.wait(); .. use the buffer contents ...
Since handlers are just function objects you can use them to do pretty much anything, such as signalling your "cp" variable that the operation has completed. For example, see the sample code at the bottom of this posting: http://article.gmane.org/gmane.comp.lib.boost.devel/155402 Cheers, Chris
