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:
_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.
