Metadata API

Metadata is extra information, generic data which can be attached to a task, a thread, a process, etc. Metadata has a type, name, and value. The value encoding depends on a metadata type. It may contain either string data or a number of integer or floating point values.

To create metadata, use the following primitives:

void __itt_metadata_add(const __itt_domain *domain, __itt_id id, __itt_string_handle *key, __itt_metadata_type type, size_t count, void *data)

void __itt_metadata_str_addA(const __itt_domain *domain, __itt_id id, __itt_string_handle *key, const char *data, size_t length)

void __itt_metadata_str_addW(const __itt_domain *domain, __itt_id id, __itt_string_handle *key, const wchar_t *data, size_t length)

void __itt_metadata_add_with_scope(const __itt_domain *domain, __itt_scope scope, __itt_string_handle *key, __itt_metadata_type type, size_t count, void *data)

void __itt_metadata_str_add_with_scopeA(const __itt_domain *domain, __itt_scope scope, __itt_string_handle *key, const char *data, size_t length)

void __itt_metadata_str_add_with_scopeW(const __itt_domain *domain, __itt_scope scope, __itt_string_handle *key, const wchar_t *data, size_t length)

The following table defines the parameters used in the Metadata API primitives.

Type Parameter Description
[in] __itt_domain* domain Metadata domain
[in] __itt_scope scope Metadata scope: task, thread, process, and global. If a scope is undefined, metadata belongs to the last task in the thread.
[in] __itt_string_handle* name Metadata name
[in] __itt_metadata_type type Metadata type; used only for numeric metadata
[in] size_t count Number of numeric metadata items [in] size_t length
[in] size_t length

Number of symbols a metadata string

[in] void *data Actual metadata (array of numerics or string)
const char *data
const wchar_t *data
