 ===== Proposal ===== ===== Proposal =====
 This RFC would add an fsync() function accepting a single parameter of a stream resource. The implementation of this function would be a thin wrapper around the standard C fsync (or equivalent _commit on Windows API, which uses an identical signature). This RFC would add an fsync() function accepting a single parameter of a stream resource.

 +The related function fdatasync() which syncs data but not necessarily metadata would also be added, however this is not supported on Windows and the proposal there is to still provide fdatasync() but merely as an alias of fsync(). On POSIX, fdatasync() is properly implemented.
