How to show function args at flowchart?

Question

The following is like reverse-engineering for code understanding. So here is the function:

void deleteTask(TaskPtr& head, const char* fullName)
{
    TaskPtr current, nodeToDelete;
    if(strcmp(head->fullName, fullName) == 0)
    {
        current = head;
        head = head->next;
        delete(current->address);
        delete(current);
        return;
    }

    for(current = head; current != NULL; current = current->next)
    {
        if(strcmp(current->next->fullName, fullName) == 0)
        {
            nodeToDelete = current->next;
            current->next = nodeToDelete->next;
            delete(nodeToDelete->address);
            delete(nodeToDelete);
            break;
        }
    }
}
