Domain API

A domain enables tagging trace data for different modules or libraries in a program. Domains are specified by unique character strings, for example TBB.Internal.Control.

Each domain is represented by an opaque __itt_domain structure, which you can use to tag each of the ITT API calls in your code.

You can selectively enable or disable specific domains in your application, in order to filter the subsets of instrumentation that are collected into the output trace capture file. Upon the first start, the application registers its domains in a configuration file of the Intel® GPA Graphics Monitor. By default, upon the first start of the application all the domains are enabled. To enable or disable domains for subsequent starts of the application, do the following before the start:

  1. Open the Graphics Monitor Launcher Screen.
  2. Click the Options button.
  3. Click the Tracing tab.
  4. Turn on or off the User Domains toggle buttons.

The overhead of a disabled domain is a single if check.

To create a domain, use the following primitives:

__itt_domain *ITTAPI__itt_domain_createA ( const char *name)

__itt_domain *ITTAPI __itt_domain_createW ( const wchar_t *name)

Or use the macro in the following way:

__itt_domain *ITTAPI __itt_domain_create (__TEXT("TBB.Internal.Control"))

For a domain name, the URI naming style is recommended, for example, com.my_company.my_application. The set of domains is expected to be static over the application's execution time, therefore, there is no mechanism to destroy a domain.

Any domain can be accessed by any thread in the process, regardless of which thread created the domain. This call is thread-safe.

Parameters of the primitives:

[in]

name

Name of domain

Usage Example

#include "ittnotify.h"
__itt_domain* pD = __itt_domain_create(__TEXT("My Domain") );
