NAME

6       wcpncpy  -  copy  a  fixed-size  string of wide characters, returning a
7       pointer to its end

SYNOPSIS

10       #include <wchar.h>
11
12       wchar_t *wcpncpy(wchar_t *dest, const wchar_t *src, size_t n);

18               _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L

DESCRIPTION

23       The wcpncpy() function is the wide-character  equivalent  of  the  stp‐
24       ncpy(3)  function.   It copies at most n wide characters from the wide-
25       character string pointed to by src, including the terminating null wide
26       (L'\0'),  to  the  array pointed to by dest.  Exactly n wide characters
27       are written at dest.  If the length wcslen(src) is smaller than n,  the
28       remaining  wide  characters  in the array pointed to by dest are filled
29       with L'\0' characters.  If the length wcslen(src) is greater  or  equal
30       to n, the string pointed to by dest will not be L'\0' terminated.
31
32       The strings may not overlap.
33
34       The programmer must ensure that there is room for at least n wide char‐
35       acters at dest.
36

RETURN VALUE

38       wcpncpy() returns a pointer to the last wide  character  written,  that
39       is, dest+n-1".
