// Example Program: T_VOID
// Description:
//  This is a test program to illustrate how to call the CTI_Run()
//  subprocedure to void a capture or credit.
//
//  To achieve this, generate a unique ID with CTI_NextUniqueId(), and
//  then populate and write a record to CTIWSHDR. Then, call CTI_Run()
//  passing in your unique ID as well as the other parameters shown.
//
//  CTI_Run() will return *On if no error was encountered, or *Off
//  if an error occurred. If an error occurred, you should look at
//  the fields in ErrorDS to retrieve information about the error.
//
//  Otherwise, you can perform a CHAIN against the CTIWSRSP physical
//  file, and retrieve the result fields.
