Expand description

Linux sys_sendto implementation

Send a message on a socket. Unlike sendmsg, this directly takes a buffer and address.

Arguments:

  • abi: LinuxRiscv64Abi context
  • trapframe: Trapframe containing syscall arguments
    • arg0: sockfd (socket file descriptor)
    • arg1: buf (pointer to data buffer)
    • arg2: len (length of data)
    • arg3: flags (send flags)
    • arg4: dest_addr (pointer to destination address, may be NULL for connected sockets)
    • arg5: addrlen (size of destination address)

Returns:

  • number of bytes sent on success
  • negative errno on error
