IT_TCPversion (stackKind; stackVersion) 
Integer
| Parameter | Type | Description | |
| stackKind | Integer |  | 0 = None, 3 = WinSock, 4 = BSD |
| stackVersion | Text | | Version number of the TCP stack |
Function result Integer Error Code
Description
The IT_TCPversion command returns information about the type of TCP stack currently in use by the 4D Internet Commands. The type of Stack varies by platform. Under Macintosh, only BSD is now supported. Under Windows, the WinSock TCP stack is supported.
stackKind returns an integer value expressing the type of TCP stack currently in use. The value returned identifies the following supported TCP stacks:
| Code | TCP Stack |
| 0 | None |
| 1 | MacTCP (Obsolete, see Compatibility note) |
| 2 | Open Transport (Obsolete, see Compatibility note) |
| 3 | WinSock |
| 4 | BSD Sockets |
Compatibility notes:
• MacTCP is no longer supported (starting from version 6.8). Therefore, the stackKind parameter will no longer return "1".
• Open Transport is no longer supported (starting from version 2004). Therefore, the stackKind parameter will no longer return "2".
stackVersion returns a Text value representing the version number of the TCP stack currently in use and identified by the stackKind parameter.
