how to bind aws_socket to network interface

[mllw]

Are there any plans to add a function that bind sockets to specify network interface?

not sure exactly what you're asking?

We have an aws_socket_bind() function.

I think the intent is for socket options to be able to specify a particular network interface that must be used. Which is problematic because socket options is a by-value structure we blindly copy everywhere and I don't think we want C-strings or byte cursor/bufs in it. Maybe there's a reasonable upperbound and it could just be a fixed size array.

I use aws-c-http to send HTTP requests.
I wanted to set the socket's option by SO_BINDTODEVICE, but I didn't find a suitable function and there was no suitable callback function to complete this setup

Is there any solution for this one? I also want to send the request through an ip address.
