WCPNCPY(3) Linux Programmer's Manual WCPNCPY(3)NAMEwcpncpy - 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 stp‐
ncpy() 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 char‐
acters at dest.
RETURN VALUEwcpncpy() returns a pointer to the last wide character written, i.e.
dest + n - 1.
CONFORMING TO
This function is a GNU extension.
