The Stdlib class exports only functions that are part of the standard C library, from the ISO-9899 standard (C99). As such, exports should be portable to any operating system supporting the standard C library, such as Microsoft Windows, as opposed to Mono.Unix.Native.Syscall which only supports Unix-like operating systems.

All public static members of this type are probably safe for multithreaded operations within managed code. (Methods which are obviously unsafe are synchronized, such as Stdlib.strerror, but any hidden dependencies between e.g. Stdlib.strerror and Stdlib.fopen are not protected.) No multithreading guarantee is made between managed and unmanaged code. Check your operating system documentation for more information.
