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.
