Virtual Table Server (VTS) Single Connection and Multiple Connection Functions

Note: The functions for multiple connections have been deprecated.

Use single connection functions if the script connects to only one Virtual Table Server. See Virtual Table Server functions (C, C#, Java) .

Use multiple connection functions if the script connects to more than one server. See Virtual Table Server (VTS) Functions for Multiple Connections (vtc and vts_multi).

Do not mix single connection functions and multiple connection functions in a script.

Most functions can be used in C language, C#, Java, and JavaScript scripts. See the individual function references for details.
