Wide Character Process Control Functions

Internationalization (I18n) Issue:

These functions are entirely similar to single byte process control functions, except they operate upon wide characters strings. To operate correctly, the underlying wchar_t * type which handles the wide character strings must be properly implemented.

I18n Solution:

Use the appropriate equivalent wide character manipulation function when reengineering an application for internationalization.

I18n Discussion:

Within an internationalized software application, it may not be necessary to convert internal programmatic strings (i.e. never displayed to the user) to wide character equivalents. To minimize the reengineering impact on the application, these functions should be researched as to the exact usage and dealt with accordingly. In the event that the process control function will never accept a wide character string, these functions need not be implemented.
