Format of a Text Log Section Header

  • Artikel

A text log section header consists of two log entries. The format of the first entry includes a ">>> " 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.

>>>  [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:

>>>  [section_title]

The format of the second entry of a section header includes a ">>> " prefix string, followed by a time_stamp field and a "Section start" string, as follows:

>>>  time_stamp Section start

The format of the time_stamp field is as follows:

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:."

>>>  [Device Install - PCI\VEN_104C&DEV_8019&SUBSYS_8010104C&REV_00\3&61aaa01&0&38]
>>>  2005/02/13 22:06:28.109: Section start
