<wchar.h>

Most of the functions, types, and constants listed below are documented in the Run-Time Library Reference, a section of the Visual C++ Programmer's Guide. Those that are not documented there are relatively new to wchar.h and are documented in the topics following this one.

Include the standard header <wchar.h> so that you can perform input and output operations on wide streams or manipulate wide strings.
