| Pingpong |
| ======== |
| |
| Pingpong is just my (Daniel's) jestful collective name on the protocols that |
| share a very similar kind of back-and-forth procedure with command and |
| responses to and from the server. FTP was previously the only protocol in |
| that family that libcurl supported, but when POP3, IMAP and SMTP joined the |
| team I moved some of the internals into a separate pingpong module to be |
| easier to get used by all these protocols to reduce code duplication and ease |
| code re-use between these protocols. |
| |
| FTP |
| |
| In 7.20.0 we converted code to use the new pingpong code from previously |
| having been all "native" FTP code. |
| |
| POP3 |
| |
| There's no support in the documented URL format to specify the exact mail to |
| get, but we support that as the path specified in the URL. |
| |
| IMAP |
| |
| SMTP |
| |
| There's no official URL syntax defined for SMTP, but we use only the generic |
| one and we provide two additional libcurl options to specify receivers and |
| sender of the actual mail. |
