Winsock Structures (Windows CE 5.0)
The following table shows the Winsock structures with a description of the purpose of each.
| Programming element | Description |
|---|---|
| addrinfo | This structure is used by the getaddrinfo function to hold host address information. |
| AFPROTOCOLS | This structure supplies a list of protocols to which application programmers can constrain queries. This structure is used for query purposes only. |
| BLOB (Windows Sockets) | This structure is derived from a binary large object (BLOB) and contains information about a block of data. |
| CSADDR_INFO | This structure contains Windows Sockets address information for a network service or name space provider. |
| fd_set | This structure is used by various Windows Sockets functions and service providers to place sockets into a set for various purposes. |
| hostent | This structure is used by functions to store information about a given host, such as host name, IP address, and so forth |
| in_addr | This structure represents a host by its Internet address. |
| in6_addr | This structure represents a host by its IPv6 address. |
| linger | This structure maintains information about a specific socket that specifies how that socket should behave when data is queued to be sent and the closesocket function is called. |
| NS_SERVICE_INFO | This structure contains information about a network service or a network service type in the context of a specified name space, or a set of default name spaces. |
| PROTOCOL_INFO | This structure contains information about a protocol. |
| protoent | This structure contains the name and protocol numbers that correspond to a given protocol name |
| servent | This structure is used to store or return the name and service number for a given service name. |
| SERVICE_ADDRESSES | This structure contains an array of SERVICE_ADDRESS data structures. |
| SERVICE_ADDRESS | This structure contains address information for a service |
| SERVICE_INFO | This structure contains information about a network service or a network service type. |
| SERVICE_TYPE_INFO_ABS | This structure contains information about a network service type. Use this structure to add a network service type to a name space. |
| SERVICE_TYPE_VALUE_ABS | This structure contains information about a network-service type value. This information may be specific to a name space. |
| sockaddr_in6 | In the Internet address family, this structure is used by Windows Sockets to specify a local or remote endpoint address to which to connect a socket |
| sockaddr_in | In the Internet address family, this structure is used by Windows Sockets to specify a local or remote endpoint address to which to connect a socket |
| SOCKADDR_STORAGE | This structure stores socket address information. |
| sockaddr | This structure varies depending on the protocol selected. |
| SOCKET_ADDRESS | This structure stores protocol-specific address information. |
| timeval | This structure is used to specify time values. |
| TRANSMIT_FILE_BUFFERS | This structure specifies data to be transmitted before and after file data during a file transfer operation. |
| WSABUF | This structure enables the creation or manipulation of a data buffer. |
| WSACOMPLETION | This structure specifies completion notification settings for I/O control calls made to a registered namespace. |
| WSADATA | This structure is used to store Windows Sockets initialization data returned by a call to WSAStartup. |
| WSANAMESPACE_INFO | This structure contains all registration information for a name space provider. |
| WSANETWORKEVENTS | This structure is used to store a socket's internal information about network events. |
| WSAOVERLAPPED | This structure provides a communication medium between the initiation of an overlapped I/O operation and its subsequent completion. |
| WSAPROTOCOL_INFO | This structure is used to store or retrieve complete information for a given protocol. |
| WSAPROTOCOLCHAIN | This structure contains a counted list of Catalog Entry identifiers that constitute a provider chain. |
| WSAQUERYSET (Windows Sockets) | This structure provides relevant information about a given service, including service class ID, service name, applicable name-space identifier and protocol information, as well as a set of transport addresses at which the service listens. |
| WSASERVICECLASSINFO | This structure contains information about a specified service class. |
