C# CreatePipe() -> Protected memory error
- by M. Dimitri
Hi all,
I trying to create a pipe using C#. The code is quite simple but I get a error saying "Attempted to read or write protected memory. This is often an indication that other memory is corrupt."
Here the COMPLETE code of my form :
public partial class Form1 : Form
{
[DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
public static extern bool CreatePipe(out SafeFileHandle hReadPipe, out SafeFileHandle hWritePipe, SECURITY_ATTRIBUTES lpPipeAttributes, int nSize);
[StructLayout(LayoutKind.Sequential)]
public struct SECURITY_ATTRIBUTES
{
public DWORD nLength;
public IntPtr lpSecurityDescriptor;
public bool bInheritHandle;
}
public Form1()
{
InitializeComponent();
}
private void btCreate_Click(object sender, EventArgs e)
{
SECURITY_ATTRIBUTES sa = new SECURITY_ATTRIBUTES();
sa.nLength = (DWORD)System.Runtime.InteropServices.Marshal.SizeOf(sa);
sa.lpSecurityDescriptor = IntPtr.Zero;
sa.bInheritHandle = true;
SafeFileHandle hWrite = null;
SafeFileHandle hRead = null;
if (CreatePipe(out hRead, out hWrite, sa, 4096))
{
MessageBox.Show("Pipe created !");
}
else
MessageBox.Show("Error : Pipe not created !");
}
}
At the top I declare : using DWORD = System.UInt32;
Thank you very much if someone can help.
