Missing scanf family of functions

[stefanct]

If there is no intention to add support for them, I think it should at least be documented as it is quite essential for parsing data in some applications. What's your stance on the issue? Is there any suggested workaround currently?

I have no stance on these functions :). I haven't developed a system that has required them, and you are the first to ask. No technical or ideological reason.

picolibc (newlib-nano) has full support. I only mention as an immediate solution - I assume you are here because you do not wish to use newlib.

[phillipjohnston]

Looking over these functions, one blocker is that I do not actually support FILE or stdin/out/err in this library, so it would be gated on having a suitable solution for that.

Some of the functions, such as sscanf and vsscanf, look like they would be suitable for implementation, however.

Yes, in this regard it is similar to some of the printf functions. sscanf is what I was after in this case. It's not a big deal for me and I can work around it.
