I'm getting weird errors from the compiler about certain win32 types that I have to declare like:

alias void (* LPWSAOVERLAPPED_COMPLETION_ROUTINE)(in DWORD, in DWORD, in LPWSAOVERLAPPED, in DWORD);


Then import certain functions like:

extern(Windows)
{
int WSASend(SOCKET s,
	LPWSABUF,
	DWORD,
	LPDWORD,
	DWORD,
	LPWSAOVERLAPPED,
	LPWSAOVERLAPPED_COMPLETION_ROUTINE);
}

And the error happens here:

if (WSASend(client.socket, &buffer, 1, &sent, 0, &client.sendoverlapped, &sendCompletion) && WSAGetLastError() != WSA_IO_PENDING)



Errors:

function network.WSASend (uint,WSABUF *,uint,uint*,uint,WSAOVERLAPPED *,int(Windows *)(HANDLE,uint,uint,int)) does not match argument types (uint,WSABUF *,int,uint*,int,WSAOVERLAPPED *,void(Windows *)(uint dwError,uint cbTransferred,WSAOVERLAPPED *lpOverlapped,uint dwFlags))

cannot implicitly convert expression (#buffer) of type WSABUF * to WSABUF *

You may want to check your source for multiple typedef's of `WSABUF'.

In some ways, DMD is fairly simple minded. Your code fails because the literal '1' is believed by DMD to be an 'int', but the type DWORD is a 'uint', so DMD complains. If you change the call literal to '1U' all will be well again.  Why DMD can't work out that if the literal as an int doesn't match, it can retry to match assuming that the literal is a uint, I haven't got a clue.

I tried '1U' with no luck, all those errors still appear.

After some searching I found this:

alias WSABUF* LPWSABUF;

I commented that out and changed all instances of LPWSABUF with WSABUF* and magically that error disappeared, but the other 3 remain.

:(
:confused:

Thanks for the help!

Thanks for the help! :D

Upon removing all LP types to type* and commented the alias', the problems disappear.

These alias' are bad, mmmkay:
alias WSAOVERLAPPED* LPWSAOVERLAPPED;
alias WSABUF* LPWSABUF;
alias void (* LPWSAOVERLAPPED_COMPLETION_ROUTINE)(in DWORD, in DWORD, in LPWSAOVERLAPPED, in DWORD);

So why is DMD choking on those aliased types?

Are these incorrect?  Thanks :-B

I understand your problems with weird type resolution in D, maybe the time will make it cleaner... I hope...

But. Why do you use WSA... thing for sockets?
There is a solid socket (and socketstream) implementation in Phobos.

I agree.  I've written a few applications using the Phobos socket libraries and they have worked perfectly.
