Re: [fuse-devel] Writing to a file while a read is blocked on same file?

[Stef B. <st...@gm...>]

Hi,

have you got an answer yet?

I've solved the same problem (read-writer ) using threads, mutexes,
condition variables etcetera.

You can find various documentation on the Internet about howto do this.

I want to write some kind of "driver" in user space which provides nodes from which I can read data if available and write some data to it. If no data is available the read shall block. In this case I still want to be able to write data to the same node. When I do this with Fuse and I am blocked waiting for a semaphore in the read function, I am not able to write any data to this node. I assume that there is only one thread for the read and write functions, am I right? Is there another way to do what I want?
