Thread: C standard library on Windows platform

I'm sorry for such a simple question ...

I'm studying C with some books and all of them mentioning about the C standard library.
But, when I look at the MSDN site there is no library reference for C. There is CRT - C Runtime Library.
Is CRT the Microsoft implementation of the standard C library?

To add to what Prelude said: Library writers sometimes add implementation specific functionality to their libraries in adition to what the C standard declares. If you want the maximum portability I sugest not using functions which are not in the standard, but there might be some tools in a specific implementation that may be helpful to you.

In the documentation itself you should see some functions marked as non-standard if they are not a part of the C standard (or at least they should be, I don't know how MSDN handles things), but all the standardized functions will be available (or should be), and produce equal results (other than undefined behavior), in any C library.

Thank you all.

As far as I can see, although there are .lib files in CRT, we use standard header files names in our source files (like stdio.h) for using functions in CRT.
Can we use .lib files directly in our source files?

And, I need to see some simple examples to understand static and dynamic library files ... can you please advise me a book for understanding of creation of .lib and .dll files and seeing their usage in my source files?

You usually never deal with DLL files directly in your code. You can manually load and unload DLLs if you want to but that is usually done by the linker when you compile your project (in Visual Studio).

.lib files are a dubious creature in Windows since they are used for both static libraries and as a way for the linker to automatically load DLLs. That's why DLLs are often accompanied by a .lib file since otherwise you would have to create code yourself that loads and unloads it.

Thanks a lot for the replies.
