# DisconnectFromTCPServer

int DisconnectFromTCPServer (unsigned int conversationHandle);

## Purpose

Terminates a connection between the client and the server.

| Note DisconnectFromTCPServer terminates only the connection conversationHandle identifies. There can be more than one conversation between a client and a server.

## Parameters

Input
Name | Type | Description
conversationHandle | unsigned integer | The conversation handle that uniquely represents the connection between the server and the client.

## Return Value

Name | Type | Description
status | integer | Return value indicating whether the function was successful. Unless otherwise stated, zero represents successful execution and a negative number represents the error code. You can call the GetTCPSystemErrorString function to obtain a system message that describes the error. The system messages can be more descriptive than the TCP Library error codes. To obtain the correct system error message, you must call GetTCPSystemErrorString immediately after calling the TCP Library function that failed. For functions that read or write data (ClientTCPRead, ClientTCPWrite, ServerTCPRead, ServerTCPWrite), if the function was successful, the return value is the number of bytes transferred. You can have a maximum of 255 concurrent conversations and up to 1,024 connections. If you exceed this limit, -kTCP_TooManyConnections will be returned. You may not be able to open the maximum number of connections allowed by LabWindows/CVI because of limitations imposed by the operating system.
