Detailed Description

The metadata API is used to attach extra information to named entities. Metadata can be attached to an identified named entity by ID, or to the current entity (which is always a task).

Conceptually metadata has a type (what kind of metadata), a key (the name of the metadata), and a value (the actual data). The encoding of the value depends on the type of the metadata.

The type of metadata is specified by an enumerated type __itt_metdata_type.

Function Documentation

__itt_metadata_add()

void ITTAPI __itt_metadata_add	(	const __itt_domain *	domain,
		__itt_id	id,
		__itt_string_handle *	key,
		__itt_metadata_type	type,

	)

Add string metadata to an instance of a named entity.

Parameters

[in]	domain	The domain controlling the call
[in]	scope	The scope of the instance to which the metadata is to be added
[in]	id	The identifier of the instance to which the metadata is to be added, or __itt_null to add to the current task
[in]	key	The name of the metadata
