wcsncpy - copy a fixed-size string of wide characters
#include <wchar.h> 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, including the terminating null wide character (L'\0'), to the array pointed to by
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 characters. If the length
wcslen(src) is greater than 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
