ASIO Compile Errors on Visual Studio 2008, 64 bit

[cheesy4poofs@…]

I've been getting and correcting these compile time errors since boost 1.34, finally decided to report them. Only occurs with Windows x64 builds.

boost/asio/detail/win_thread.hpp(151) : error C2664: 'QueueUserAPC' : cannot convert parameter 1 from 'void (cdecl *)(ULONG)' to 'PAPCFUNC'

None of the functions with this name in scope match the target type

boost/asio/detail/win_iocp_io_service.hpp(142) : error C2664: 'GetQueuedCompletionStatus' : cannot convert parameter 3 from 'DWORD *' to 'PULONG_PTR'

Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

boost/asio/detail/win_iocp_io_service.hpp(430) : error C2664: 'GetQueuedCompletionStatus' : cannot convert parameter 3 from 'DWORD *' to 'PULONG_PTR'

Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

The fixes are:

win_thread.hpp:151

::QueueUserAPC((PAPCFUNC) apc_function, thread_, 0);

win_iocp_io_service.hpp:135

#if (WINVER < 0x0500)

ULONG_PTR completion_key = 0;

#else

ULONG_PTR completion_key = 0;

#endif

win_iocp_io_service.hpp:422

#if (WINVER < 0x0500)

ULONG_PTR completion_key = 0;

#else

ULONG_PTR completion_key = 0;

#endif

This looks suspiciously like you're not using a recent enough value for WINVER. From memory, Win64 requires 0x502 or later (i.e. Windows Server 2003).

Closing since there have been no further comments. The 64-bit Windows regression tests show no failures. Furthermore, the code has since been changed to default to the newer types (e.g. ULONG_PTR rather than ULONG) if WINVER is not defined.
