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



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

SYNOPSIS
       #define _GNU_SOURCE
       #include <wchar.h>

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

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 L'\0' character, 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  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.

CONFORMING TO
       This function is a GNU extension.
