I've actually just about finished a fairly complete implementation of the standard C headers (incorporating stuff from DMD and DMC when needed). If you're so inclined, they're available here: http://home.f4.ca/sean/d/stdc.zip I'm updating them quite frequently, so if you grab them be sure to check back often. That said, in testing I noticed that you don't need getErrno and setErrno to operate on this value. Simply defining: extern (C) int errno; is enough. And if that doesn't work, try this: extern (C) int* _errno(); Both are exposed in the DMC libraries. If you're on Linux, you may have to do some digging, but the first declaration should likely work there too. Sean |

If you're on Linux, you may have to do some digging, but the first declaration should likely work there too. thanks. I'll try accessing errno directly. on phobos there is the errno.c with getErrno() and one of the std declares it as extern(C) getErrno() (something like that) but now I have to revert to 102 (see my post on the bugs group) (I just downloaded your stdc) Ant |

It works for me, but then I'm not running off a default install. BTW, as promised, I just uploaded a new version of the stdc stuff. I had to change all the wchar stuff back to wchar_t because the sizes are different on Windows vs. Unix :p Sean |
