ИМЯ

       wcsncpy - copy a fixed-size string of wide characters

БИБЛИОТЕКА

       Standard C library (libc, -lc)

СИНТАКСИС

       #include <wchar.h>

       wchar_t *wcsncpy(wchar_t dest[restrict .n],
                        const wchar_t src[restrict .n],
                        size_t n);

ОПИСАНИЕ

       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 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 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 dest.

ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ

       wcsncpy() returns dest.
