ASIO IoControlCommand Type Requirement needs undocumented expression get()

[Kevin Arunski <kevin.arunski@…>]

I am attempting to create a type that conforms to IoControlCommand to pass to the io_control member function in the socket classes.

The compilation fails due to a missing expression a.get(). It's not clear from the documentation what this expression should return.

I've encountered this on Linux and Mac OS X and various versions of g++ 4.x

Test program, fails compilation with 'struct MyIoControl has no member get'

Implement automatic resizing of the bucket array in the internal hash maps. This is to improve performance for very large numbers of asynchronous operations and also to reduce memory usage for very small numbers. A new macro BOOST_ASIO_HASH_MAP_BUCKETS may be used to tweak the sizes used for the bucket arrays.
