Input and Output Primitives Manager sync - Schedule file system updates

RTEMS POSIX API User's Guide

void sync(void);

NONE

The sync service causes all information in memory that updates file systems to be scheduled for writing out to all file systems.

The writing of data to the file systems is only guaranteed to be scheduled upon return. It is not necessarily complete upon return from sync.
