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.
