I was suggesting getting posix_ipc or sysv_ipc to compile against a
compatibility library (Cygwin?) under Windows. It sounds like you're
proposing something totally different, no?
OK I see. But probably I do not want to use Cygwin because that would
create another dependency. I understand that posix_ipc/sysv is not
natively supported under windows. What about this:
- create a wrapper, using ctypes, /windll / cdll/ to access API functions
- use CreateFileMapping on the page file to create shared memory (a la
windows: http://msdn.microsoft.com/en-us/library/aa366537.aspx)
- use CreateEvent/WaitForSingleObject for signaling
(http://msdn.microsoft.com/en-us/library/ms682396(VS.85).aspx)
- these should be enough to implement shared memory functions and
message queues under windows, and that might be a quick solution at
least for me.
- it might also be used to emulate the same posix_ipc interface, without
any external dependency added (cygwin).
All I care about is to create a working message queue. But if you think
that this ctypes hack would be useful for other users, then I can try to
implement it.
I must tell you that I'm not very familiar with C programming (it was a
long time ago...) and I do not own MSVC.
(Hmm, can I compile this with mingw?)
