WCSNCPY(3)                Linux Programmer's Manual               WCSNCPY(3)

NAME         top

       wcsncpy - copy a fixed-size string of wide characters

SYNOPSIS         top

       #include <wchar.h>

       wchar_t *wcsncpy(wchar_t *dest, const wchar_t *src, size_t n);

DESCRIPTION         top

       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.

RETURN VALUE         top

       wcsncpy() returns dest.
