Wsasocket vista

This issue occurs because the child process does not release the handle for a long time. By default, socket handles are inheritable. When a child process is created, the child process inherits the socket handle from the parent process.

When the parent process tries to close the socket, it waits until the child process releases the handle. However, the child process does not release the handle for a long time.

Therefore, the application stops responding. You can download this service pack from the following Microsoft website:. A supported hotfix is available from Microsoft. However, this hotfix is intended to correct only the problem that is described in this article.

If this section does not appear, contact Microsoft Customer Service and Support to obtain the hotfix. All of the state information associated with a socket is held in common across all the descriptors because the socket descriptors are duplicated and not the actual socket.

For example, a setsockopt operation performed using one descriptor is subsequently visible using a getsockopt from any or all descriptors.

Both the source process and the destination process should pass the same flags to their respective WSASocket function calls. A process can call closesocket on a duplicated socket and the descriptor will become deallocated. The underlying socket, however, will remain open until closesocket is called by the last remaining descriptor. Issuing either of these calls using any of the shared descriptors cancels any previous event registration for the socket, regardless of which descriptor was used to make that registration.

For situations when such tight coordination is required, developers would be advised to use threads instead of separate processes. Windows 8. The parameters for creating a root or leaf depend on the underlying protocol. Before it returns control, WSHOpenSocket2 should allocate necessary memory for a socket-specific context structure, set a notification bitmask, and set the name of the transport driver that handles this socket. Otherwise, a memory leak can occur.

A socket type that provides sequenced, reliable, two-way, connection-based byte streams with an OOB data transmission mechanism. A socket type that supports datagrams, which are connectionless, unreliable buffers of a fixed typically small maximum length.

A socket type that provides a raw socket that allows an application to manipulate the next upper-layer protocol header. A socket type that provides a reliable message datagram. An example of this type is the Pragmatic General Multicast PGM multicast protocol implementation in Windows, often referred to as reliable multicast programming. This type value is only supported if the Reliable Multicast Protocol is installed. This protocol value is supported on Windows XP and later.

The PGM protocol for reliable multicast. This protocol value is only supported if the Reliable Multicast Protocol is installed. A successful WSAStartup call must occur before using this function. The specified address family is not supported. A blocking Windows Sockets 1. An invalid argument was supplied. The service provider returned an invalid or incomplete procedure table to the WSPStartup.

The service provider failed to initialize. This error is returned if a layered service provider LSP or namespace provider was improperly installed or the provider fails to operate correctly.
