DESCRIPTION
     The functions implement string manipulation operations over wide
     character strings.  For a detailed description, refer to documents for
     the respective single-byte counterpart, such as memchr(3).

SEE ALSO

     stpncpy(3), strcasecmp(3), strcat(3), strchr(3), strcmp(3), strcpy(3),
     strcspn(3), strdup(3), strlcat(3), strlcpy(3), strlen(3), strncat(3),
     strncmp(3), strncpy(3), strnlen(3), strpbrk(3), strrchr(3), strspn(3),
     strstr(3)

STANDARDS
     These functions conform to ISO/IEC 9899:1999 ("ISO C99"), with the
     exception of wcpcpy(), wcpncpy(), wcscasecmp(), wcsdup(), wcsncasecmp(),
     and wcsnlen(), which conform to IEEE Std 1003.1-2008 ("POSIX.1"); and
     wcslcat(), wcslcpy(), and wmempcpy(), which are extensions.
