23    wchar.h

Palm OS® Protein C/C++ Compiler Language & Library Reference

Palm OS® Developer Suite

The <wchar.h> header is included for compliance purposes only.

None of the C wide-char (wchar_t) functionality is supported in Palm OS. (In fact, the wchar_t type is not even used by Palm OS since it can vary in size from 8-bits to 32-bits depending on the compiler.) For safe manipulation of text regardless of the device's character encoding, use the Palm OS String and Text Managers; see Exploring Palm OS: Text and Localization.
