NAME strncat - concatenate a string with part of another
char *strncat(char *restrict
, const char *restrict
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

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.
No errors are defined.
The following sections are informative.
APPLICATION USAGE None.
