Socket Functions
accept() |
An incoming connection is acknowledged and associated with an immediately created socket. The original socket is returned to the listening state. |
bind() |
Assign a local name to an unnamed socket. |
closesocket() |
Remove a socket descriptor from the per-process object reference table. Only blocks if SO_LINGER is set. |
connect() |
Initiate a connection on the specified socket. |
getpeername() |
Retrieve the name of the peer connected to the specified socket descriptor. |
getsockname() |
Retrieve the current name for the specified socket. |
getsockopt() |
Retrieve options associated with the specified socket descriptor. |
htonl() |
Convert a 32-bit quantity from host byte order to network byte order. |
htons() |
Convert a 16-bit quantity from host byte order to network byte order. |
inet_addr() |
Converts a character string representing a number in the Internet standard ".'' notation to an Internet address value. |
inet_ntoa() |
Converts an Internet address value to an ASCII string in ".'' notation i.e. "a.b.c.d''. |
ioctlsocket() |
Provide control for descriptors. |
listen() |
Listen for incoming connections on a specified socket. |
ntohl() |
Convert a 32-bit quantity from network byte order to host byte order. |
ntohs() |
Convert a 16-bit quantity from network byte order to host byte order. |
recv()* |
Receive data from a connected socket. |
recvfrom()* |
Receive data from either a connected or unconnected socket. |
select()* |
Perform synchronous I/O multiplexing. |
send()* |
Send data to a connected socket. |
sendto()* |
Send data to either a connected or unconnected socket. |
setsockopt() |
Store options associated with the specified socket descriptor. |
shutdown() |
Shut down part of a full-duplex connection. |
socket() |
Create an endpoint for communication and return a socket descriptor. |
*These functions may block if acting on a blocking socket
Database Functions
gethostbyaddr()* |
Retrieve the name(s) and address corresponding to a network address. |
gethostname() |
Retrieve the name of the local host. |
gethostbyname()* |
Retrieve the name(s) and address corresponding to a host name. |
getprotobyname()* |
Retrieve the protocol name and number corresponding to a protocol name. |
getprotobynumber()* |
Retrieve the protocol name and number corresponding to a protocol number. |
getservbyname()* |
Retrieve the service name and port corresponding to a service name. |
getservbyport()* |
Retrieve the service name and port corresponding to a port. |

Windows Sockets Asynchronous Extensions
WSAAsyncGetHostByAddr() |
A set of functions which provide asynchronous versions of the standard Berkeley getXbyY() functions. For example, the WSAAsyncGetHostByName() function provides an asynchronous message based implementation of the standard Berkeley gethostbyname() function. |
WSAAsyncSelect() |
Perform asynchronous version of select(). |
WSACancelAsyncRequest() |
Cancel an outstanding instance of a WSAAsyncGetXByY() function. |
WSACancelBlockingCall() |
Cancel an outstanding "blocking" API call. |
WSACleanup() |
Sign off from the underlying Windows Sockets DLL. |
WSAGetLastError() |
Obtain details of last Windows Sockets API error |
WSAIsBlocking() |
Determine if the underlying Windows Sockets DLL is already blocking an existing call for this thread. |
WSASetBlockingHook() |
"Hook" the blocking method used by the underlying Windows Sockets implementation. |
WSASetLastError() |
Set the error to be returned by a subsequent WSAGetLastError(). |
WSAStartup() |
Initialize the underlying Windows Sockets DLL. |
WSAUnhookBlockingHook() |
Restore the original blocking function. |
