# Multi Processor Trace Example
|
|
|
|
In this example, the application in `main.cc` initializes and registers a tracer
|
|
provider from the [OpenTelemetry
|
|
SDK](https://github.com/open-telemetry/opentelemetry-cpp). The `TracerProvider`
|
|
is connected to two `processor-exporter` pipelines - for exporting
|
|
simultaneously to `StdoutSpanExporter` and `InMemorySpanExporter`. The
|
|
application then calls a `foo_library` which has been instrumented using the
|
|
[OpenTelemetry
|
|
API](https://github.com/open-telemetry/opentelemetry-cpp/tree/main/api).
|
|
Resulting telemetry is directed to stdout through the StdoutSpanExporter, and
|
|
saved as a variable (vector of spans) through `InMemorySpanExporter`.
|
|
|
|
See [CONTRIBUTING.md](../../CONTRIBUTING.md) for instructions on building and
|
|
running the example.
