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

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

       #include <wchar.h>

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

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

           Since glibc 2.10:
               _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
           Before glibc 2.10:

       The wcpncpy() function is the wide-character  equivalent  of  the  stp-
       ncpy(3)  function.   It copies at most n wide characters from the wide-
       character string pointed to by src, including the terminating null wide
       (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 L'\0' characters.  If the length wcslen(src) is  greater  than  or
       equal to n, the string pointed to by dest will not be L'\0' terminated.

       The strings may not overlap.

       The programmer must ensure that there is room for at least n wide char-
       acters at dest.

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

   Multithreading (see pthreads(7))
       The wcpncpy() function is thread-safe.
