ihft::engine

This module contains a main function for ihft applications.

namespace ihft::engine
{
    class cpus_config;
    class task_storage;

    using register_tasks_callback_t = types::function_ref<bool(cpus_config const&, task_storage&, std::atomic_bool const&)>;
    using invalid_config_callback_t = types::function_ref<void()>;

    int engine_main(int const argc, char const * const argv[], register_tasks_callback_t, invalid_config_callback_t);
}

It provides a comprehensive functionality for:

• parse and validate an application configuration
• validation of the application launch platform
• complex signal handler initialization
• thread initialization and processor bindings
• binding user tasks to execution threads
• waiting for the end of the application
