It's the same thing for the fseek function for the offset argument.

This is effectively a bug requesting large file support on 32-bit
platforms, which makes it a duplicate of the previously closed bug
#38758, bug #40726, bug #43865, and probably others besides. The open
bug that deals with this is bug #27792, which includes a patch to
implement LFS.

Simply changing the function to take a float wouldn't solve the
problem, since the underlying file I/O APIs all use 32-bit integers as
well. This requires work both at the ext/standard and stream level.

It's also worth noting that this already works just fine on 64-bit
platforms.
