NAME
strncat - concatenate a string with part of another
SYNOPSIS
#include <string.h> char *strncat(char *restrict s1, const char *restrict s2, size_t n);
DESCRIPTION
The strncat() function shall append not more than n bytes (a null byte and bytes that follow it are not
appended) from the array pointed to by s2 to the end of the string pointed to by s1. The initial byte of
s2 overwrites the null byte at the end of s1. A terminating null byte is always appended to the result.
If copying takes place between objects that overlap, the behavior is undefined.
RETURN VALUE
The strncat() function shall return s1; no return value shall be reserved to indicate an error.
