Looking at the header (wchar.h) I don't think wcscpy_s is available for the Pocket PC.

hello john,

i found:
errno_t __cdecl wcscpy_s(wchar_t * restrict, rsize_t, const wchar_t * restrict);

in pellec/include/wchar.h

and in the PelleHelp for wcscpy the first sentence:

"Purpose:
Copies a wide string. The safer wcscpy_s function is also available."

Hello Thomas,

If you look in that header you will find

/* more secure C functions (TR24731-1) */
#if __STDC_WANT_LIB_EXT1__ && !defined(_WINCE)

which excludes that function from WINCE.

The reason not all functions are included in WINCE is to save room, I've heard.
