- I clarified in the docs that CURLOPT_SEEKFUNCTION should return 0 on success

  and 1 on fatal errors. Previously it only mentioned non-zero on fatal

  errors. This is a slight change in meaning, but it follows what we've done

  elsewhere before and it opens up for LOTS of more useful return codes

  whenever we can think of them...

- Fix curl_off_t definition for builds done using Sun compilers and a

  non-configured libcurl. In this case curl_off_t data type was gated

primary connection (meaning the control connection in the FTP case). Future

versions of libcurl may support more purposes. It passes the newly created

socket descriptor so additional setsockopt() calls can be done at the user's

discretion.  A non-zero return code from the callback function will signal an

unrecoverable error to the library and it will close the socket and return

\fICURLE_COULDNT_CONNECT\fP.  (Option added in 7.15.6.)

discretion.  Return 0 (zero) from the callback on success. Return 1 from the

callback function to signal an unrecoverable error to the library and it will

close the socket and return \fICURLE_COULDNT_CONNECT\fP.  (Option added in

7.15.6.)

.IP CURLOPT_SOCKOPTDATA

Pass a pointer that will be untouched by libcurl and passed as the first

argument in the sockopt callback set with \fICURLOPT_SOCKOPTFUNCTION\fP.
