wcsncpy - copy a fixed-size string of wide characters
wchar_t *wcsncpy(wchar_t *dest, const wchar_t *src, size_t n);
The wcsncpy() function is the wide-character equivalent of the strncpy(3) function. It
copies at most n wide characters from the wide-character string pointed to by src, includ-
ing the terminating null wide character (L'\0'), to the array pointed to by dest. Exactly
n wide characters are written at dest. If the length wcslen(src) is smaller than n, the
remaining wide characters in the array pointed to by dest are filled with null wide char-
acters. If the length wcslen(src) is greater or equal to n, the string pointed to by dest
will not be terminated by a null wide character.
The strings may not overlap.
The programmer must ensure that there is room for at least n wide characters at dest.
wcsncpy() returns dest.
Multithreading (see pthreads(7))
The wcsncpy() function is thread-safe.
