I mean, it looks the same in both places, and sftp.h is a C file.

It makes sense for a C++ file to say "I'm using this C interface", but it's silly for all C headers to have to say "If you're not using a C compiler, this C file describes C code".

Also, it alerted you to the fact that the contents of sftp.cpp are not declared in this header.

sftp.h is from the (C) sftp library and does not describe the contents of sftp.cpp (the interface is defined here). sftp.cpp is the sftp support in sbbs_t, sftp.h is the sftp library.

It's not the same... sftp_dirdescriptor_t has the state of a directory descriptor, and path_map_t describes a mapping between an sftp path and a "Synchronet path".

Because it's allowed in library and/or directory names, but SFTP reserves that character as a path separator. Since lib/dir names can't have a division slash, it's a lossless, reversible translation that looks very close or identical to what the Sysop intended by putting a slash in the name.

I'm using the sftp library (and newifc) to play with library interface concepts before I start hacking up ciolib (or start on a new ciolib replacement).

One of those things is planned to be "proper" C++ support instead of having C++ code call C functions... I'm generally becoming more and more of the opinion that extern "C" blocks in C++ code indicate bad choices, and am trying to work out what the alternative good choice looks like.

It looks like in the code now, shell_login defaults to false and is only set to true under a specific SSH-login. Is there some other place shell_ogin is being set to true now for non-SSH logins?

I was thinking there could be something like `enum ssh_session_type { sshe_none, ssh_shell, ssh_ftp } ssh_login;`

And then `if (ssh_login != ssh_ftp)` (in the subsequent now-conditional blocks that are to only execute for non-SFTP session) seems clearer to me.
