NAME

wcsncat - concatenate two wide-character strings

SYNOPSIS

bash

#include <wchar.h>

bash

wchar_t *wcsncat(wchar_t \ndest\n[restrict .\nn\n],\n
\n                 const wchar_t \nsrc\n[restrict .\nn\n],\n
\n                 size_t \nn\n);

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.
