[vox-tech] errno upon success (a real success)?

i've read that system and library calls can set errno, even when they're

for example, info glibc mentions that sqrt() can return a perfectly
valid value in case of an error and also set errno.  i assume they mean
when you do something like trying to take the square root of a negative
number or a "machine infinity".

but this example is kind of a stretch.  some people may consider taking
the sqrt of infinity to be an error in the first place, and therefore,
approrpriate for setting errno, whether inf is a valid return value or
not.  but whether you agree with this or not, nevermind.  my question

does anyone know of an example where errno is set upon success that may
not be as much of a stretch as taking the square root of infinity?
