Hi Poly/ML,
Is it possible to retrieve a socket from a file descriptor in Standard ML or Poly/ML?
E.g., if Posix.FileSys.ST.isSock (Posix.FileSys.fstat fd) is true, then what can I do to fd to use functions in the Socket structure on it?
Cheers, Ramana
I don't think it's possible to create a socket from a file descriptor in ML. While they are the same in Unix they are different in Windows. It's possible to go the other way using Socket.ioDesc. Maybe someone else will have a solution.

Would it help if you could derive a path from the file descriptor? It's horribly OS-specific: https://stackoverflow.com/questions/1188757/getting-filename-from-file-descr...

Thanks David and Phil for the information and suggestion. Since it's not straightforward in SML I'm working around having to do it at all. (For context, I was trying to use the open file descriptor that refers to a listening socket that the FastCGI spec says an application is given on startup.)
