From ecd75e8cb803f7b938c44e8594222406404a955c Mon Sep 17 00:00:00 2001 From: Alessandro Ghedini Date: Wed, 28 Dec 2011 15:01:05 +0100 Subject: examples: add a couple of simple pop3s examples These examples show how to fetch a single message (RETR command) and how to list all the messages in a given mailbox (LIST command), with authentication via SSL. They were both based on the https.c example. --- docs/examples/pop3s.c | 68 +++++++++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 68 insertions(+) create mode 100644 docs/examples/pop3s.c (limited to 'docs/examples/pop3s.c') diff --git a/docs/examples/pop3s.c b/docs/examples/pop3s.c new file mode 100644 index 000000000..4a2e8fdeb --- /dev/null +++ b/docs/examples/pop3s.c @@ -0,0 +1,68 @@ +/*************************************************************************** + * _ _ ____ _ + * Project ___| | | | _ \| | + * / __| | | | |_) | | + * | (__| |_| | _ <| |___ + * \___|\___/|_| \_\_____| + * + * Copyright (C) 1998 - 2011, Daniel Stenberg, , et al. + * + * This software is licensed as described in the file COPYING, which + * you should have received as part of this distribution.
