API Tutorial Lesson 05 - Logging custom information

Our transaction manager's call log stores information about all API calls handled. In some situations (as for example, for debugging or auditing purposes) it might be useful to register additional data in this call log. That is the only purpose of the 'Log' transaction, defined by the 'LogAllow' and 'LogCommit' APIs. Their usage is depicted in this lesson's figure: 'LogAllow' requires an operation handle representing a Valid login, a solution token, and the custom text to be added to the log as parameters. The 'LogCommit' API takes the operation handle returned by the call of the 'LogAllow' API as its only parameter.
