FileStream only works with regular files.

Hiii,

I am using xenomai as rtos on ubuntu
we have written a small application for pipe communication

Test.h

class Test : public WithTestLayout<TopWindow> {
public:
typedef Test CLASSNAME;
		Test();
	FileStream RTtoUI;
	struct RT2UI
		{
			uint  Status;
			
		};

		RT2UI rt2ui;
		RT2UI ReadArray[3];
		void readpipe();
	
};

main.cpp



void Test::readpipe()
{String str;
RTtoUI.Open("/dev/rtp0" ,0);
	{
	str << "opened" << "\n";
	lineedit.Paste ( str.ToWString() );
	}
	else
	{
	str << "cannot open" << "\n";
	lineedit.Paste ( str.ToWString() );
	}
RTtoUI.Read(0, &ReadArray, sizeof ( ReadArray ) );
	str <<  ReadArray[0].Status << "\n";
	lineedit.Paste ( str.ToWString() );
}

while running this on ubuntu through U++ am getting following error
assertion failed in /root/upp/core/BlockStream.cpp
(IsOpen() && (style & STRM_READ));

The same code was working fine in fedora OS

Actually in ubuntu /dev/rtp0 is not opening through upp.
