[Mono-dev] Mono C# + IOCTL

[Alex]

Yea I just used pseudo code. The problem is that mono c# does not support PF_PACKET so the only way around it
is to pretty much implement it from scratch using marshaling and unamanged code imports. I'm half way there my code looks
something like that for now:
[DllImport("libc.so.6")]
    public static extern int socket(int domain, int type, int protocol);
    [DllImport("libc.so.6")]
    public static extern int send(int s, [MarshalAs(UnmanagedType.LPArray)] byte[] buf, int len, int flags);
    [DllImport("libc.so.6")]
    public static extern int recv(int s, [MarshalAs(UnmanagedType.LPArray)] byte[] buf, int len, int flags);

This allows me to create the socket and send/recv data. Still need to implement bind. 
I wish there was a way to link that fd returned by socket to the native c# socket class but up to my knowledge there isn't.

This is not the way to use ioctl in C. You need additional parameters.
See netdevice(7).
