Function check_pending_signals 

Source 
pub fn check_pending_signals() -> Result<bool, KernelError>
Expand description

Check for and deliver any pending signals on the current process/thread.

This function should be called on the syscall return path (or on return from interrupt) to deliver signals at a safe point. It dequeues the lowest-numbered pending unblocked signal and, if a user-space handler is registered, constructs a signal frame so the handler executes on return to user mode.

§Returns

  • Ok(true) if a signal was delivered (thread context was modified).
  • Ok(false) if no deliverable signal was pending.
  • Err(...) on failure.
