Method: PG::Connection#socket

Defined in:
ext/pg_connection.c

#socket ⇒ Fixnum

Returns the socket’s file descriptor for this connection. IO.for_fd() can be used to build a proper IO object to the socket. If you do so, you will likely also want to set autoclose=false on it to prevent Ruby from closing the socket to PostgreSQL if it goes out of scope. Alternatively, you can use #socket_io, which creates an IO that’s associated with the connection object itself, and so won’t go out of scope until the connection does.

Note: On Windows the file descriptor is not really usable, since it can not be used to build a Ruby IO object.

Returns:

  • (Fixnum)
