strncat - concatenate part of two strings
#include <string.h> char *strncat(char *s1, const char *s2, size_t n);
The strncat() function appends 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 behaviour is undefined.
The strncat() function returns s1; no return value is reserved to indicate an error.
No errors are defined.
