Hi,
I am trying write and read commands to pipe /dev/rtp0 and rtp1..
can anyone provide an example for this...
I tried with FileOut method but did'nt get the thing..

FileOut file1;
file1.Open ( "/dev/rtp1 " );
file1.Put(&wr1,sizeof(wr1));

where wr1 is

 struct write {
       int command;
       int data;
   };
write wr1;

Also is " file1.Put(&wr1,sizeof(wr1)); " is the right method to write data to any file other than /dev..????

pipe does not have support in U++. You have to use C API.

Thanks Mirek.
Is there any example so that i can know the method of using C API in upp..

Also if i want to write a data declared in structure into a file does this method holds good?

file1.Put(&wr1,sizeof(wr1));
