Work with user variables
In addition to the variables provided by KINGSTAR, you can create your own variables, record them into a log, or display them in KINGSTAR Analysis Console to track their changes. In this section, you'll learn how to create user variables and set their attributes.
Functions
AddVariable: adds a user-defined variable.
GetVariable: gets the details of a user-defined variable. It is called when an application or function wants to use the user variables added by another program.
GetVariables: gets the list of user-defined variables.
RemoveVariable: removes a user-defined variable.
Code
We break the steps down into a few parts so you can easily learn how each function works.
Before we start, in Log.cpp, add the following preprocessor directives and function. We include the header wchar.h because wide characters will be used; using namespace std is for strings use. We are writing code in the CreateUserVariables function. The first line of code, RtPrintf("Work with user variables.\n\n");, displays the message that describes what this function is going to do.
NOTE: Some header files overlaps with others in different sections.
#include "RT_Project_01.h"
#include <wchar.h>
using namespace std;
int CreateUserVariables()
{
RtPrintf("Work with user variables.\n\n");
return 0;
}
