Revision history for Perl extension Curl::easy.
|
||||
Check out the file README for more info.
|
||||
|
||||
1.0.2 Tue Oct 10 2000:
|
||||
- runs with libcurl 7.4
|
||||
- modified curl_easy_getinfo(). It now calls curl_getinfo() that has
|
||||
been added to libcurl in version 7.4.
|
||||
|
||||
1.0.1 Tue Oct 10 2000:
|
||||
- Added some missing features of curl_easy_setopt():
|
||||
- CURLOPT_ERRORBUFFER now works by passing the name of a perl
|
||||
variable that shall be crated and the errormessage (if any)
|
||||
be stored to.
|
||||
- Passing filehandles (Options FILE, INFILE and WRITEHEADER) now works.
|
||||
Have a look at test.pl to see how it works...
|
||||
|
||||
- Added a new function, curl_easy_getinfo(), that for now always
|
||||
returns the number of bytes that where written to disk during the last
|
||||
download. If the curl_easy_getinfo() function is included in libcurl,
|
||||
(as promised by Daniel ;-)) i will turn this into just a call to this
|
||||
function.
|
||||
|
||||
1.0 Thu Oct 5 2000:
|
||||
- first released version
|
||||
- runs with libcurl 7.3
|
||||
- some features of curl_easy_setopt() are still missing:
|
||||
- passing function pointers doesn't work (options WRITEFUNCTION,
|
||||
READFUNCTION and PROGRESSFUNCTION).
|
||||
- passing FILE * pointers doesn't work (options FILE, INFILE and
|
||||
WRITEHEADER).
|
||||
- passing linked lists doesn't work (options HTTPHEADER and
|
||||
HTTPPOST).
|
||||
- setting the buffer where to store error messages in doesn't work
|
||||
(option ERRORBUFFER).

README for Perl extension Curl::easy.
|
||||
|
||||
The perl module Curl::easy provides an interface to the cURL library "libcurl".
|
||||
See http://curl.haxx.se/ for more information on cURL and libcurl.
|
||||
|
||||
This module requires libcurl and the corresponding headerfiles to be
|
||||
installed. You then may install this module via the usual way:
|
||||
|
||||
perl Makefile.PL
|
||||
make
|
||||
make test
|
||||
make install
|
||||
|
||||
The module provides the same functionality as libcurl provides to C programs,
|
||||
please refer to the documentation of libcurl.
|
||||
|
||||
A short example how to use the module may be found in test.pl.
