Hi All,
I am trying to obtain socket descriptor from a Socket Transport
object. However, I am unable to obtain a valid descriptor, and I was
wondering if some one could point out what I am doing wrong. Here is
what I am doing to get socket descriptor:
1. First, an nsiSocketTransport object is created in Javascript Code
using a SocketTransportService object:
var currTransport = mySockService.createTransport(null, 0,
currHostName, currPort, null);
2. Now, I am passing currTransport to a C++ xpcom component as an
object with interface nsISocketTransport. In the C++ code, I call
GetFileDescriptor on the currTransport object.
NS_IMETHODIMP getDescFromTransport(nsISocketTransport *sockTransport)
{
PRFileDesc *fd;
...
if (NS_FAILED(sockTransport->GetFileDescriptor(&fd)))
{
return NS_OK;
}
...
}
I noticed that after calling GetFileDescriptor, fd is set to a null
value.
I think fd should not contain a null value and should point to the
socket descriptor for the socket connection that has been established.
Please let me know if this is the expected behaviour. Do I need to do
something more with sockTransport in order to obtain a valid file
descriptor using GetFileDescriptor()?
Thanks,
Abhijit
