All pipes intances are busy

[Arif Liminto]

Hi I got a project which involves interprocess communication. I uses pipes because it's only happend in one machine. It seems everything should be perfect. However, When I try to connect The Client and The Server. I always have an Error number 231 ( All pipe instances are busy) when I try to create file in client side. Client --> Create File, Write File Server --> Create Named Pipes, Read File here is some of the code in my programs

m_hPipeHandle = INVALID_HANDLE_VALUE;
m_hPipeHandle = CreateFile(ISOCOMSPIPE,GENERIC_WRITE,FILE_SHARE_WRITE,NULL,OPEN_EXISTING,FILE_ATTRIBUTE_NORMAL,NULL);

if(m_hPipeHandle == INVALID_HANDLE_VALUE)
{
int iRet = GetLastError();
printf("Error number %d",iRet);
}

closeHandle(m_hPipeHandle);

Is there anything wrong in the attributes/ missing attributes when I want to create the file ? Thx
