    Command:

    wcpncpy

    
    
    
    

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

    DESCRIPTION

           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.
    
    
    

    RETURN VALUE

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

    ATTRIBUTES

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