wcsncat(3) Library Functions Manual wcsncat(3)
NAME
wcsncat - concatenate two wide-character strings
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <wchar.h>
wchar_t *wcsncat(wchar_t dest[restrict .n],
const wchar_t src[restrict .n],
size_t n);
DESCRIPTION
The wcsncat() function is the wide-character equivalent of the strn-
cat(3) function. It copies at most n wide characters from the wide-
character string pointed to by src to the end of the wide-character
string pointed to by dest, and adds a terminating null wide character
(L'\0').
The strings may not overlap.
The programmer must ensure that there is room for at least wc-
slen(dest)+n+1 wide characters at dest.
RETURN VALUE
wcsncat() returns dest.
