wcsncat(3)

wcsncat3

Concatenate two wide-character strings

Usage

#include <wchar.h>

wchar_t *wcsncat(size_t n; wchar_t *restrict dest, const wchar_t src[restrict n], size_t n);

Library

Standard C library (libc, -lc)

Overview

The wcsncat() function is the wide-character equivalent of the strncat(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 wcslen(dest)+n+1 wide characters at dest.

Return value

wcsncat() returns dest.
