Author: Instructor (talk, contrib)


This plug-in provides access to a number of "standard" functions from C Standard Library, which programmers are used to from their C/C++ compilers (and other languages), but which are not available in NSIS by default. In order to keep the plug-in size as small as possible and for maximum compatibility, the Visual C++ Run-Time v6.0 (MSVCRT.DLL), which is included with all versions of Windows (since Windows 2000), is used - instead of linking the Visual C++ Run-Time library into the plug-in DLL.

Additionally this plug-in provides wrappers for the SHFileOperation function. Moreover it provides a method for launching programs in a non-elevated way (user context) from an elevated installer (admin mode) on UAC-enabled systems. See this thread for details.
