19. String Length (Without Null-Terminator)

size_t length = wcsnlen(wstr, 10);  // Get the length of a wide character string without counting the null-terminator

20. String Memory Set

wmemset(wstr, L'a', 10);  // Set a specified number of wide characters in a wide character string to a given value

21. String Memory Copy

wmemcpy(wstr1, wstr2, 10);  // Copy a specified number of wide characters from one wide character string to another

22. String Memory Move

wmemmove(wstr1, wstr2, 10);  // Move a specified number of wide characters from one wide character string to another, overlapping if necessary

23. String Memory Compare

int result = wmemcmp(wstr1, wstr2, 10);  // Compare a specified number of wide characters in two wide character strings

24. String Find First Of

wchar_t *result = wcschr(wstr, L'a');  // Find the first occurrence of a wide character in a wide character string
