Since the SSH (v2 at least, as I don't know v1) protocol allows channel requests with custom type and payload,
I was thinking it would be nice to make this available in the public API of libssh.
What do you think?
I guess it would look like:
int ssh//channel//open//custom(ssh//channel channel, ssh//string type, ssh//buffer payload)
Thank you very much.

This is already supported, see

and the RFCs.

Thank you for the reply.
I wasn't talking about "subsystems" nor "requests we send inside channels", (5.4. "Channel-Specific Requests" in RFC 4254)
I probably should have put more details in my question.
I was talking about the type of a channel itself. (5.1. "Opening a Channel" in RFC 4254)
For exemple, for sftp, we have to open a channel of type "session" and then send a request inside this channel to ask the server if it supports the "sftp subsystem"...
I would like libssh to allow for channels that are not of type "session" but of an arbitrarily type.
in channels.c the non-exposed function static int channel//open(ssh//channel channel, const char **type, int window, int maxpacket, ssh//buffer payload) is called multiple times with hardcoded channel types like "session", "direct-tcpip", "forwarded-tcpip", "x11" ...
Basically I am suggesting writing a function
int ssh//channel//open//custom(ssh//channel channel, ssh//string type, ssh//buffer payload)
in addition to the existing
int ssh//channel//open//session(ssh//channel channel)
int ssh//channel//open//auth//agent(ssh//channel channel)
int ssh//channel//open//forward(ssh//channel channel, const char **remotehost, int remoteport, const char **sourcehost, int local port)
...
Feel free to ask me any question if it is still unclear.
Thank you.
