Expand description

Linux epoll_pwait implementation (stub)

Like epoll_wait but with signal mask. This is a stub implementation that immediately returns 0 (no events ready).

Arguments:

  • abi: LinuxRiscv64Abi context
  • trapframe: Trapframe containing syscall arguments
    • arg0: epfd (epoll file descriptor)
    • arg1: events (pointer to epoll_event array)
    • arg2: maxevents (maximum number of events)
    • arg3: timeout (timeout in milliseconds)
    • arg4: sigmask (signal mask)

Returns:

  • number of ready events
  • usize::MAX (Linux -1) on error
