The below table captures the function that are to be called from the application logic.

API Functions

Function

Description

rs_vp_init

To initialize the VP stack.

rs_vp_process

To be called periodically to process the block operations.
Callback Functions

Function

Description

rcb_vp_blk_error_info

Called when blocks error occurs.

Error Code

  • Every API’s for the VP returns some success or failure values. Please refer below section,

Implementation Guide

This section explains how to implement the VP using the RAPIDSEA stack, the steps to be followed are

  • Initialize the VP

  • Import flint project.

  • Call the vp process periodically to execute the VP blocks.

  • Blocks execute based on the flint project
