Struct FdArgs

pub struct FdArgs {
    pub fd: Fd,
    pub length: u64,
    pub buffer_addr: u64,
    pub length_addr: u64,
}

Arguments shared by read, write and inherited fd syscalls

Fields

fd: Fd

For each and write syscalls, this contains the file descriptor to use

length: u64

Length to read or length to write for read/write syscalls. Inherited fd syscall will ignore this field.

buffer_addr: u64

VM address to keep returned data

length_addr: u64

VM address for a input / output length buffer. For read / write syscalls, this contains the actual data length. For inherited fd syscall, this contains the number of file descriptors.
