History of Changes
** curl 7.7 DOES NOT currently WORK. **
Daniel (20 February 2001)
- Added the docs/examples/win32sockets.c file for our windows friends.
- Linus Nielsen Feltzing provided brand new TELNET functionality and
improvements:
* Negotiation is now passive. Curl does not negotiate until the peer does.
* Possibility to set negotiation options on the command line, currently only
XDISPLOC, TTYPE and NEW_ENVIRON (called NEW_ENV).
* Now sends the USER environment variable if the -u switch is used.
* Use -t to set telnet options (Linus even updated the man page, awesome!)
- Haven't done this big changes to curl for a while. Moved around a lot of
struct fields and stuff to make multiple connections get connection specific
data in separate structs so that they can co-exist in a nice way. See the
mailing lists for discussions around how this is gonna be implemented. Docs
and more will follow.
Studied the HTTP RFC to find out better how persistant connections should
work. Seems cool enough.
Daniel (19 February 2001)
- Bob Schader brought me two files that help set up a MS VC++ libcurl project
easier. He also provided me with an up-to-date libcurl.def file.
- I moved a bunch of prototypes from the public <curl/curl.h> file to the
library private urldata.h. This is because of the upcoming changes. The
low level interface is no longer being planned to become reality.
Daniel (15 February 2001)
- CURLOPT_POST is not required anymore. Just setting the POST string with
CURLOPT_POSTFIELDS will switch on the HTTP POST. Most other things in
libcurl already works this way, i.e they require only the parameter to
switch on a feature so I think this works well with the rest. Setting a NULL
string switches off the POST again.
- Excellent suggestions from Rich Gray, Rick Jones, Johan Nilsson and Bjorn
Reese helped me define a way how to incorporate persistant connections into
libcurl in a very smooth way. If done right, no change may have to be made
to older programs and they will just start using persistant connections when
applicable!
Daniel (13 February 2001)
- Changed the word 'timeouted' to 'timed out' in two different error messages.
Suggested by Larry Fahnoe.
Version 7.6.1

When used with -s it makes curl show error message if it fails.
If this option is used twice, the second will again disable show error.
.IP "-t/--upload"
.B Deprecated. Use '-T -' instead.
Transfer the stdin data to the specified file. Curl will read
everything from stdin until EOF and store with the supplied name. If
this is used on a http(s) server, the PUT command will be used.
.IP "-t/--telnet-option <OPT=val>"
Pass options to the telnet protocol. Supported options are:
TTYPE=<term> Sets the terminal type.
XDISPLOC=<X display> Sets the X display location.
NEW_ENV=<var,val> Sets an environment variable.
.IP "-T/--upload-file <file>"
Like -t, but this transfers the specified local file. If there is no
file part in the specified URL, Curl will append the local file
