Detailed Description

Trace (set of streams).

A trace is a set of streams with properties:

In the illustration above, notice that a trace is an instance of a trace class and that it contains streams.

Borrow the class of a trace with bt_trace_borrow_class() and bt_trace_borrow_class_const().

A trace is a trace IR data object.

A trace is a shared object: get a new reference with bt_trace_get_ref() and put an existing reference with bt_trace_put_ref().

Some library functions freeze traces on success. The documentation of those functions indicate this postcondition. With a frozen trace, you can still:

Create streams from it with bt_stream_create() or bt_stream_create_with_id().
Add a destruction listener to it with bt_trace_add_destruction_listener().

The type of a trace is bt_trace.

A trace contains streams. All the streams of a given trace have unique numeric IDs. Get the number of streams in a trace with bt_trace_get_stream_count(). Borrow a specific stream from a trace with bt_trace_borrow_stream_by_index(), bt_trace_borrow_stream_by_index_const(), bt_trace_borrow_stream_by_id(), or bt_trace_borrow_stream_by_id_const().

Create a default trace from a trace class with bt_trace_create().

Add to and remove a destruction listener from a trace with bt_trace_add_destruction_listener() and bt_trace_remove_destruction_listener().

Properties

A trace has the following properties:

Optional: Name

Name of the trace.

Use bt_trace_set_name() and bt_trace_get_name().

Optional: UUID

UUID of the trace.

The trace's UUID uniquely identifies the trace.

Use bt_trace_set_uuid() and bt_trace_get_uuid().

Optional: Environment

Generic key-value store which describes the environment of the trace (for example, the system's hostname, its network address, the tracer's name and version, and the rest).

Trace environment keys are strings while values are signed integers or strings.

Set a trace environment entry's value with bt_trace_set_environment_entry_integer() and bt_trace_set_environment_entry_string().

Get the number of environment entries in a trace with bt_trace_get_environment_entry_count().

Borrow an environment entry from a trace with bt_trace_borrow_environment_entry_value_by_name_const().

Optional: User attributes

User attributes of the trace.

User attributes are custom attributes attached to a trace.

Use bt_trace_set_user_attributes(), bt_trace_borrow_user_attributes(), and bt_trace_borrow_user_attributes_const().
