Using the API to Access the VTS Table

LoadRunner enables you to include API functions in a Vuser script to access the VTS table, and to manipulate the data in the table.

For details on the VTS API functions, see the Function Reference.

Note: Many of these functions have both lrvtc and vtc versions.

The lrvtc functions are LoadRunner integrated calls that automatically evaluate LoadRunner parameters and store results to LoadRunner parameters. It is recommended that you use these lrvtc functions in your Vuser scripts if you are using a single VTS server.

The vtc functions are raw and application independent functions, for use when working with multiple VTS servers. These functions have been deprecated and will be removed in a future version. Therefore, it is recommended to work only with the respective lrvtc function.
