setsockopt

public static int setsockopt(int fd,
                             int level,
                             int optname,

                             int optlen)

Set socket FD's option OPTNAME at protocol level LEVEL to *OPTVAL (which is OPTLEN bytes long). Returns 0 on success, -1 for errors.

listen
```
public static int listen(int fd,
                         int n)
```
Prepare to accept connections on socket FD. N connection requests will be queued before further requests are refused. Returns 0 on success, -1 for errors.

accept
```
public static int accept(int fd,
                         Socket.sockaddr addr,
                         org.graalvm.nativeimage.c.type.CIntPointer addr_len)
```
Await a connection on socket FD. When a connection arrives, open a new socket to communicate with it, set *ADDR (which is *ADDR_LEN bytes long) to the address of the connecting peer and *ADDR_LEN to the address's actual length, and return the new socket's descriptor, or -1 for errors.

accept4

public static int accept4(int fd,
                          Socket.sockaddr addr,
                          org.graalvm.nativeimage.c.type.CIntPointer addr_len,
                          int flags)

Similar to 'accept' but takes an additional parameter to specify flags.

shutdown
```
public static int shutdown(int fd,
                           int how)
```
Shut down all or part of the connection open on socket FD. HOW determines what to shut down: SHUT_RD = No more receptions; SHUT_WR = No more transmissions; SHUT_RDWR = No more receptions or transmissions. Returns 0 on success, -1 for errors.

sockatmark
```
public static int sockatmark(int fd)
```
Determine whether socket is at a out-of-band mark.

isfdtype
```
public static int isfdtype(int fd,
                           int fdtype)
```
FDTYPE is S_IFSOCK or another S_IF* macro defined in ; returns 1 if FD is open on an object of the indicated type, 0 if not, or -1 for errors (setting errno).
