STANDARDS

The wmemchr(), wmemcmp(), wmemcpy(), wmemmove(), wmemset(), wcscat(), wcschr(), wcscmp(), wcscpy(), wcscspn(), wcslen(), wcsncat(), wcsncmp(), wcsncpy(), wcspbrk(), wcsrchr(), wcsspn() and wcsstr() functions were first introduced in ISO/IEC 9899/AMD1:1995 (“ISO C90, Amendment 1”) and conform to ISO/IEC 9899:1999 (“ISO C99”). Part of them: wmemmove(), wcscat(), wcscpy(), wcsncat() and wcsncpy() were modified in ISO/IEC 9899:1999 (“ISO C99”) and gained the restrict keyword in parameter list, this new version is present in NetBSD.

The wcswcs() function conforms to X/Open Portability Guide Issue 4, Version 2 (“XPG4.2”), it is recommended to use technically equivalent wcsstr() for maximum portability.

The wcsnlen() function conforms to IEEE Std 1003.1-2008 (“POSIX.1”).

The wcslcat() and wcslcpy() functions are NetBSD extensions.
