Memory leak from getaddrinfo() function

[kurz-m]

Nice work Azer!

However, you are leaking memory from this line, because of getaddrinfo():

ft_ping/srcs/main.c

Line 92 in cfbdf60

if (getaddrinfo(argv[1], NULL, &hints, &res) != 0) {

From the man page:

The getaddrinfo() function allocates and initializes a linked list of addrinfo structures, one for each network address that matches node and service, subject to any restrictions imposed by hints, and returns a pointer to the start of the list in res. The items in the linked list are linked by the ai_next field.

Fix:
Call freeaddrinfo() on error and before exiting the process.

The freeaddrinfo() function frees the memory that was allocated for the dynamically allocated linked list res.

The project is still under progress and I did not check for leaks yet
But that's good to know, thank you.
