Exposes StartedEvent as public and removes lifetimes (#193)

When this was first written there was concern that we could
create memory leaks by allowing the event to be ended without
calling _itt_event_end_ptr. However based on documentation
at docs/src/ittapi/event-api.rst we've concluded that calling
__itt_event_end_ptr does no ptr work as we are actually dealing
with integer handles.

Closes #188

Intel® Instrumentation and Tracing Technology (ITT) and Just-In-Time (JIT) APIs

Build Status CodeQL Package on conda-forge Package on PyPI Package on crates.io OpenSSF Scorecard

This repository contains the following profiling APIs:

  • Instrumentation and Tracing Technology (ITT) API
    Powers your application to generate and control the collection of trace data during its execution, seamlessly integrating with Intel tools.
  • Just-In-Time (JIT) Profiling API
    Reports detailed information about just-in-time (JIT) compiled code, enabling you to profile the performance of dynamically generated code.

The ITT/JIT APIs consist of two parts:

  • Static Part
    An open-source static library that you compile and link with your application.
  • Dynamic Part
    A tool-specific shared library that collects and writes trace data. You can find the reference implementation of the dynamic part as a Reference Collector here.

Build

To build the library:

  • Get general development tools, including C/C++ Compiler
  • Install Python 3.6 or later
  • Install CMake 3.5 or later
  • For a Windows* system, install one of these:
  • To enable support for Fortran, install the Intel Fortran Compiler
  • To list available build options execute: python buildall.py -h
usage: buildall.py [-h] [-d] [-c] [-v] [-pt] [-ft] [--force_bits]

optional arguments:
  -h, --help      show this help message and exit
  -d, --debug     specify debug build configuration (release by default)
  -c, --clean     delete any intermediate and output files
  -v, --verbose   enable verbose output from build process
  -pt, --ptmark   enable anomaly detection support
  -ft, --fortran  enable fortran support
  --force_bits    specify bit version for the target
  --vs            specify visual studio version (Windows only)
  --cmake_gen     specify cmake build generator (Windows only)
