+# libcurl examples
+
+This directory is for libcurl programming examples. They are meant to show
+some simple steps on how you can build your own application to take full
+advantage of libcurl.
+
+If you end up with other small but still useful example sources, please mail
+them for submission in future packages and on the website.
+
+## Building
+
+The `Makefile.example` is an example Makefile that could be used to build
+these examples. Just edit the file according to your system and requirements
+first.
+
+Most examples should build fine using a command line like this:
+
+    `curl-config --cc --cflags --libs` -o example-my example.c
+
+Some compilers do not like having the arguments in this order but instead
+want you do reorganize them like:
+
+    `curl-config --cc` -o example-my example.c `curl-config --cflags --libs`
+
+**Please** do not use the `curl.se` site as a test target for your libcurl
+applications/experiments. Even if some of the examples use that site as a URL
+at some places, it does not mean that the URLs work or that we expect you to
+actually torture our website with your tests. Thanks.
+
+## Examples
+
+Each example source code file is designed to be and work stand-alone and
+rather self-explanatory. The examples may at times lack the level of error
+checks you need in a real world, but that is then only for the sake of
+readability: to make the code smaller and easier to follow.

+ * multi socket API usage with epoll and timerfd
+ * </DESC>
+ */
+/* Example application source code using the multi socket interface to
+ * download many files at once.
+ *
+ * This example features the same basic functionality as hiperfifo.c does,
+ * but this uses epoll and timerfd instead of libevent.
+ *
+ * Written by Jeff Pohlmeyer, converted to use epoll by Josh Bialkowski
+
+Requires a Linux system with epoll
+
+When running, the program creates the named pipe "hiper.fifo"
+
+Whenever there is input into the fifo, the program reads the input as a list
+of URL's and creates some new easy handles to fetch each URL via the
+curl_multi "hiper" API.
+
+
+Thus, you can try a single URL:
+  % echo http://www.yahoo.com > hiper.fifo
+
+Or a whole bunch of them:
+  % cat my-url-list > hiper.fifo
+
+The fifo buffer is handled almost instantly, so you can even add more URL's
+while the previous requests are still being downloaded.
+
+Note:
+  For the sake of simplicity, URL length is limited to 1023 char's !
+
+This is purely a demo app, all retrieved data is simply discarded by the write
+callback.

+/* <DESC>
+ * multi socket interface together with libev
+ * </DESC>
+ */
+/* Example application source code using the multi socket interface to
+ * download many files at once.
+ *
+ * This example features the same basic functionality as hiperfifo.c does,
+ * but this uses libev instead of libevent.
+ *
+ * Written by Jeff Pohlmeyer, converted to use libev by Markus Koetter
+
+Requires libev and a (POSIX?) system that has mkfifo().
+
+This is an adaptation of libcurl's "hipev.c" and libevent's "event-test.c"
+sample programs.
+
+When running, the program creates the named pipe "hiper.fifo"
+
+Whenever there is input into the fifo, the program reads the input as a list
+of URL's and creates some new easy handles to fetch each URL via the
+curl_multi "hiper" API.
+
+
+Thus, you can try a single URL:
+  % echo http://www.yahoo.com > hiper.fifo
+
+Or a whole bunch of them:
+  % cat my-url-list > hiper.fifo
+
+The fifo buffer is handled almost instantly, so you can even add more URL's
+while the previous requests are still being downloaded.
+
+Note:
+  For the sake of simplicity, URL length is limited to 1023 char's !
+
+This is purely a demo app, all retrieved data is simply discarded by the write
+callback.

+/* Example application source code using the multi socket interface to

+ *
+ * Written by Jeff Pohlmeyer
+
+ Requires glib-2.x and a (POSIX?) system that has mkfifo().
+
+ This is an adaptation of libcurl's "hipev.c" and libevent's "event-test.c"
+ sample programs, adapted to use glib's g_io_channel in place of libevent.
+
+ When running, the program creates the named pipe "hiper.fifo"
+
+ Whenever there is input into the fifo, the program reads the input as a list
+ of URL's and creates some new easy handles to fetch each URL via the
+ curl_multi "hiper" API.
+
+
+ Thus, you can try a single URL:
+ % echo http://www.yahoo.com > hiper.fifo
+
+ Or a whole bunch of them:
+ % cat my-url-list > hiper.fifo
+
+ The fifo buffer is handled almost instantly, so you can even add more URL's
+ while the previous requests are still being downloaded.
+
+ This is purely a demo app, all retrieved data is simply discarded by the write
+ callback.
