Hi, I was writing a script for automated cross-build (Linux -> win64) for bitcoin (https://github.com/delirium---/bqt-autobuild) and met some issues with building the client. One is solved in attached commit https://github.com/delirium---/bitcoin/commit/b95e6376d083dc904722c4b5ddd7954a3a44826d
DWORD and DWORD_PTR have same size of 32bit systems but different on 64bit.
According to the MSDN docs, it should be PDWORD_PTR, right? I'm looking at: http://msdn.microsoft.com/en-us/library/windows/desktop/ms683213(v=vs.85).aspx
Right, actually that the main thing:
function gets pointers to DWORD_PTRs (PDWORD_PTR is DWORD_PTR *), and arguments are DWORDs and not DWORD_PTRs. On 32bit it is ok as sizeof(DWORD) == sizeof(DWORD_PTR), but on 64bit it is not ok. That is why I changed type of dwProcessAffinityMask and dwSystemAffinityMask from DWORD to DWORD_PTR. Do not be afraid of _PTR suffix, DWORD_PTR is not a pointer, but an unsigned integer and is really the same as DWORD on a 32bit platform.
