Function sys_accept 

pub fn sys_accept(abi: &mut LinuxRiscv64Abi, trapframe: &mut Trapframe) -> usize

Linux sys_accept implementation (mock)

Accepts a connection on a socket. This is a mock implementation that creates a new pipe and returns it as a “connected” socket fd.

Arguments:

• abi: LinuxRiscv64Abi context
• trapframe: Trapframe containing syscall arguments
  • arg0: sockfd (socket file descriptor)
  • arg1: addr (pointer to socket address structure for peer)
  • arg2: addrlen (pointer to size of address structure)

Returns:

• new socket file descriptor on success
• usize::MAX (Linux -1) indicating failure
