I don't believe so. Not only does this hack depend on knowing the
internals of FILE (which are intentionally opaque on musl); it also
depends on the assumption that the data is still present in the buffer
after it's consumed, which is invalid in general.

No idea why programmers insist on doing stuff like this rather than
fixing their design issues...
