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, includ‐
       ing 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 char‐
       acters.  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.

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

CONFORMING TO
