wcpncpy(3)



NAME

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

SYNOPSIS

   #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)):

   wcpncpy():
       Since glibc 2.10:
           _POSIX_C_SOURCE >= 200809L
       Before glibc 2.10:
           _GNU_SOURCE

DESCRIPTION

   The  wcpncpy()  function  is  the  wide-character  equivalent  of   the
   stpncpy(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
   characters at dest.

RETURN VALUE

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