DESCRIPTION
These functions implement string manipulation operations over wide-char- acter strings. For a detailed description, refer to the documents for the respective single-byte counterpart, such as memchr(3). The wcswcs() function is not a part of ISO/IEC 9899:1990 (``ISO C90'') and ISO/IEC 9899/AMD1:1995 (``ISO C90, Amendment 1''), the wcsstr() function is strongly recommended to be used.

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(), wcslcpy() and wmempcpy() functions are NetBSD extensions. NetBSD 10.99 July 30, 2023 NetBSD 10.99
