Documentation

Overview

Package os provides Go bindings for the os framework.

Coordinate the scheduling and synchronization of your app’s tasks, and log information to the console to diagnose issues.

Essentials

Logs

  • Logging: Capture telemetry from your app for debugging and performance analysis using the unified logging system. (Os_signpost_id_t)

Task Management

  • Workgroups: Schedule one or more threads to run at regular intervals and before specific deadlines.
  • Synchronization: Access low-level synchronization mechanisms to control state across threads.

Memory

  • os_proc_available_memory: Determines the amount of memory available to the current app.
  • Os_block_t: A block that takes no arguments and returns no value.
  • Os_function_t: A pointer to a function.
  • Os_release
  • Os_retain
