[Click] receiving data into a buffer

[sam barker]

Hi Beyers,

Basically,I will be sending the data [say 128 bits] through a socket
routine[ outside of click.

So in my config file can if I have

Socket(TCP, 127.0.0.1,1322)->[0]my_element

and in my_element.cc file if I have


void myelement::push(int port, Packet *p)
{
.....
  if (port == 0) {
    // First input port
    method0(p);
  } else if (port == 1) {
    // Second input port
    method1(p);
  }
....
}

void myelement::method0(Packet *p)
{
//here if I say
    char *x=(char *)p->data()

}
then x will be the pointer to 128 bits which is received?


Also if I want to send 128 bit through click to a program outside click
can I write my own socket element just to send ?

Cheers,
Sam
