@ -21,6 +21,31 @@ Differences between current and Android 2.2:
- <unistd.h>: add missing declaration for truncate(). The implementation
was already here since Android 1.5.
- <wchar.h>: small fixes to really support wchar_t in Bionic (not there yet).
the size of wchar_t is still 32-bit (decided by the compiler)
WCHAR_MIN: changed from 0 to INT_MIN
WCHAR_MAX: changed from 255 to INT_MAX
wcpcpy(), wcpncpy(), wcscat(), wcschr(), wcscmp(),
wcscpy(), wcscspn(), wcsdup(), wcslcat(), wcslcpy(),
wcslen(), wcsncat(), wcsncmp(), wcsncpy(), wcsnlen(),
wcspbrk(), wcsrchr(), wcsrchr(), wcsspn(), wcsstr(),
wcstok(), wcswidth(), wmemchr(), wmemcmp(), wmemcpy(),
wmemmove(), wmemset(): Added proper implementations.
wcscasecmp(), wcsncasecmp(): Added implementation limited
to ASCII codes for lower/upper.
wcscoll(): added dummy implementation that calls wcscmp()
wcsxfrm(): added dummy implementation that calls wcsncpy()
NOTE: Technically, this breaks the ABI, but we never claimed to support
wchar_t anyway. The wchar_t support is still *NOT* official at this
point. We need better multi-byte support code, and wprintf/wscanf
stuff too.
