This topic describes the constants that are defined in the Httptrace.h header file.
Tracing Constants
| Constant | Bitmask | Description |
|---|---|---|
| HTTP_TRACE_EVENT_FLAG_STATIC_DESCRIPTIVE_FIELDS | 0x01 | If the dwFlags member of an HTTP_TRACE_EVENT structure is set to this value, indicates that the pProviderGuid, pAreaGuid, and pszEventName members of that structure, as well as the pszName and pszDescription members in each HTTP_TRACE_EVENT_ITEM element of that structure, are static. In this case, the memory for all of these members is available and immutable for the lifetime of the process and, therefore, does not ever need to be copied. |
Tracing GUIDs
The following constants are used with the IHttpTraceContext::SetTraceConfiguration method. Verify that a module includes the Initguid.h file when you use these GUIDs.
