StdUtils plug-in

Author: Instructor (talk, contrib)

This plug-in provides access to a number of "standard" functions from C Standard Library. In order to keep the plug-in size as small as possible, the Visual C++ Run-Time v6.0 (MSVCRT.DLL), which is included with all versions of Windows since Windows 2000, is used.
