17 getpeername() returns the name of the peer connected to socket s. The
18 int pointed to by the namelen parameter should be initialized to indi‐
19 cate the amount of space pointed to by name. On return it contains the
20 actual size of the name returned (in bytes), prior to any truncation.
21 The name is truncated if the buffer provided is too small.

24 If successful, getpeername() returns 0; otherwise it returns −1 and
25 sets errno to indicate the error.
