Add a test for std.fs.File's
setEndPos
(which is a simple wrapper aroundstd.posix.ftruncate
) to exercise some success and failure paths.Explicitly check that the
ftruncate
length isn't negative when interpreted as a signed value. This avoids having to decode overloadedEINVAL
errors.Add errno handling to Windows path to map INVALID_PARAMETER to FileTooBig.
Fixes #22960
