@brief Public User API functions and types
@mainpage
The Instrumentation and Tracing Technology API (ITT API) is used to
annotate a user's program with additional information
that can be used by correctness and performance tools. The user inserts
calls in their program. Those calls generate information that is collected
at runtime, and used by Intel(R) Threading Tools.
@section API Concepts
The following general concepts are used throughout the API.
@subsection Unicode Support
Many API functions take character string arguments. On Windows, there
are two versions of each such function. The function name is suffixed
by W if Unicode support is enabled, and by A otherwise. Any API function
that takes a character string argument adheres to this convention.
@subsection Conditional Compilation
Many users prefer having an option to modify ITT API code when linking it
inside their runtimes. ITT API header file provides a mechanism to replace
ITT API function names inside your code with empty strings. To do this,
define the macros INTEL_NO_ITTNOTIFY_API during compilation and remove the
static library from the linker script.
@subsection Domains
[see domains]
Domains provide a way to separate notification for different modules or
libraries in a program. Domains are specified by dotted character strings,
e.g. TBB.Internal.Control.
A mechanism (to be specified) is provided to enable and disable
domains. By default, all domains are enabled.
@subsection Named Entities and Instances
Named entities (frames, regions, tasks, and markers) communicate
information about the program to the analysis tools. A named entity often
refers to a section of program code, or to some set of logical concepts
that the programmer wants to group together.
Named entities relate to the programmer's static view of the program. When
the program actually executes, many instances of a given named entity
may be created.
The API annotations denote instances of named entities. The actual
named entities are displayed using the analysis tools. In other words,
the named entities come into existence when instances are created.
Instances of named entities may have instance identifiers (IDs). Some
API calls use instance identifiers to create relationships between
different instances of named entities. Other API calls associate data
with instances of named entities.
Some named entities must always have instance IDs. In particular, regions
and frames always have IDs. Task and markers need IDs only if the ID is
needed in another API call (such as adding a relation or metadata).
The lifetime of instance IDs is distinct from the lifetime of
instances. This allows various relationships to be specified separate
from the actual execution of instances. This flexibility comes at the
expense of extra API calls.
The same ID may not be reused for different instances, unless a previous
[ref] __itt_id_destroy call for that ID has been issued.
