Hey, it works! However, what happens when the socket is no longer
referenced? In slang.txt it says


  Although the preceding example closed the file via fclose, there is no
  need to explicitly close a file because S-Lang will automatically
  close the file when it is no longer referenced.  Since the only
  variable to reference the file is fp, it would have automatically been
  closed when the function returned.


It seems this is achieved in slstdio.c by storing all streams in the array
SL_File_Table and by the line
   cl->cl_destroy = destroy_file_type;

Maybe the SL_File_Table could be used for sockets as well - socket()
returns a file descriptor which can be converted to a stream with fdopen(),
and slstdio.c provides some functions for this: open_file_type() calls
fdopen() and stores the stream in the table and _SLstdio_fdopen() calls
open_file_type() (which is static).

It seems open_file_type creates a FILE_POINTER_TYPE which is an instance
of the "File_Type" class or whatever, so when it's no longer referenced the
file would be closed.

BTW has anyone gotten the mysql module to compile?
