Expand description

Linux sys_getsockopt implementation (mock)

Gets socket options. This is a mock implementation that writes dummy data and succeeds to allow applications to proceed.

Arguments:

  • abi: LinuxRiscv64Abi context
  • trapframe: Trapframe containing syscall arguments
    • arg0: sockfd (socket file descriptor)
    • arg1: level (protocol level)
    • arg2: optname (option name)
    • arg3: optval (pointer to option value buffer)
    • arg4: optlen (pointer to option length)

Returns:

  • 0 on success
