The obvious problem being that while extensions are fine when implementing someone else's standard, they set a dangerous precedent when establishing your own--does the presence of msleep in std.c.time mean that all D implementations need that function there? I assume since these headers are in std.c it should be apparent that that they are an implementation of the C spec and any extensions are obviously non-portable, but a D programmer without a C background may not know which functions are standard and which are not. The C headers in Ares are a strict implementation of the C standard (with the exception of alloca and one or two others--clearly marked by a version(DigitalMars)) and are fairly complete. They're available here if anyone wants them: http://svn.dsource.org/projects/ares/trunk/src/ares/std/c/ I've eyeballed the headers in DMC and everything seems to be supported, though there may be some gaps with GDC. I'll see about submitting a sleep function for std.thread--the implementations for Windows and most Unices are quite short.

I don't mind the existence of extensions, but what we should not do is leave such core functionality as an extension in the std C library. It should be available (and specified) in the D standard library. So please go ahead with such std.thread submission :) . -- Bruno Medeiros - CS/E student "Certain aspects of D are a pathway to many abilities some consider to be... unnatural."Walter Bright wrote:I think the C headers in Phobos are more representative of the C headers in DMC than they are a strict adherence to the C standard.

I had a feeling msleep wasn't common at all, in fact I was surprised at it's presence in std.c.time. Another function which is sometimes present on unix systems is "nanosleep".
