Re: FIFO: Resource temporarily unavailable

Hi,

I'm new to this forum and to working with FIFO's, but have a 'hard' question :confused:.

Sometimes when I want to write to a FIFO, I get the error: "Resource temporarily unavailable".

My code:

...  
  assert(state == st_open);
  
  c = ::write(fd, buf, count);
  if (c == -1) {
    PM_DEBUG("Error writing to fifo, error: %s", strerror(errno));
  }
...

- Most important: What's wrong here?
- Is a FIFO stored in RAM?
- Can a FIFO ever get full? And how can a see / adjust the size of a FIFO?

Hope you can help me with this.
