How do you programmatically distinguish between Checkout and Borrow date time?

Summary

How do you programmatically distinguish between Checkout and Borrow date time?

Question

In our product, we're creating a report at the client side to show the list of nodes that use floating licenses. In the table of the report, we have a Checkout column and a Borrow column. As far as we understand, someone can checkout and at a later time to borrow, so the two columns can be different. How can they get the two values using LM_USERS struct and lc_userlist method? It seems to only have one time value, which we assume is the checkout time? How can we get the borrow time?

If we use lc_userlist like:

LM_USERS *users = lc_userlist(job, (LM_CHAR_PTR)"XYZ");

And then iterate the users like:

while (users)
{
if (users->name[0] == 0)
{
// Special record.
numberOfAvailableLicenses = users->nlic;
dateTime = UnixEpoch.AddSeconds(static_cast<double>(users->time));

users = users->next;

continue;
}

// How do you find the borrow time here for each user (if they have borrowed a license?)
DateTime checkoutDateTime = UnixEpoch.AddSeconds(static_cast<double>(users->time));

users = users->next;
}

What example code illustrates how to do this?

Answer

You can use users->linger (a structure member of LM_USERS) to distinguish between Checkout and Borrow. Using this structure member, you can find out the borrow time for each user.
LM_USERS *users = lc_userlist(job, feature_name);
if (users->next)
{
        while (users->next)
        {    
            users = users->next;
            printf("Linger is : %d\n", users->linger);
        }
}

Additional Information

To find out the checkout time:
chk_time = localtime(&users->time);
printf("checkout time for feature %s is %2d:%02d:%02d\n",
                         feature , chk_time->tm_hour, chk_time->tm_min,
                         chk_time->tm_sec);


To find out the borrow checkout time:
chk_time = localtime(&users->time);
printf("borrow time for feature %s is %2d:%02d:%02d\n",
                         feature , chk_time->tm_hour, chk_time->tm_min,
                         chk_time->tm_sec);


To find Expiration time for borrow feature:
int tNow = ((difftime( (users->linger + users->time), time(NULL) ))/3600);
printf("Feature %s Expire after %d hours\n",feature, tNow);


The below code combines the above to find out checkout time,borrow checkout time and expiration time.
while (users->next)
{    
      users = users->next;
      chk_time = localtime(&users->time);
      if(users->linger)
      {
         int tNow = ((difftime( (users->linger + users->time), time(NULL) ))/3600);
         printf("borrow time for feature %s is %2d:%02d:%02d\n",
                         feature , chk_time->tm_hour, chk_time->tm_min,
                         chk_time->tm_sec);
         printf("Feature %s Expire after %d hours\n",feature, tNow);
       }
       else
       {
          printf("checkout time for feature %s is %2d:%02d:%02d\n",
                         feature , chk_time->tm_hour, chk_time->tm_min,
                         chk_time->tm_sec);
       }
}
