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



NAME
       wcsncpy - copy a fixed-size string of wide characters

SYNOPSIS
       #include <wchar.h>

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

DESCRIPTION
       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
       wcsncpy() returns dest.
