  # Format of a Text Log Section Header
  
  
  A *text log section header* consists of two log entries. The format of the first entry includes a "&gt;&gt;&gt; " prefix string, followed by a *section_title* field and an *instance_identifier* field. In the following example, the text in italic font style is a placeholder for section-specific text that is supplied by a section creator, and the text in bold font style is supplied by SetupAPI logging.
  
  ```cpp
  >>>  [section_title - instance_identifier] 
  ```
  
  The *section_title* field is always present and provides a title for the operation that is associated with the section.
  
  The *instance_identifier* provides an identifier that, ideally, uniquely identifies the instance of the operation. If the *instance_identifier* field is not present, the format of the first entry of a section header is as follows:
  
  ```cpp
  >>>  [section_title] 
  ```
  
  The format of the second entry of a section header includes a "&gt;&gt;&gt; " prefix string, followed by a *time_stamp* field and a "Section start" string, as follows:
  
  ```cpp
  >>>  time_stamp Section start
  ```
  
  The format of the *time_stamp* field is as follows:
  
  ```cpp
  yyyy/mm/dd hh:mm:ss.sss:
  ```
  
  where the *time_stamp* subfields are as follows:
  
  -   *yyyy* is the 4-digit year, *mm* is the 2-digit month, and *dd* is the 2-digit day
  
  -   The local time is based on a 24-hour clock, where *hh* is the 2-digit hour, *mm* is the 2-digit minute, *ss* is the 2-digit number of seconds, and sss is the 3-digit number of milliseconds.
  
  The following is an example of a typical section header that the user-mode Plug and Play (PnP) manager would create to group installation operations for a PCI device. The *section_title* field is "Device Install," the *instance_identifier* field is the device instance identifier "PCI\\VEN_104C&DEV_8019&SUBSYS_8010104C&REV_00\\3&61aaa01&0&38," and the *time_stamp* field is "2005/02/13 22:06:28.109:."
  
  ```cpp
  >>>  [Device Install - PCI\VEN_104C&DEV_8019&SUBSYS_8010104C&REV_00\3&61aaa01&0&38]
  >>>  2005/02/13 22:06:28.109: Section start
  ```
