Synchronize filesystem updates
#include <unistd.h> void sync( void );
Use the -l c option to qcc to link against this library. This library is usually included automatically.
The sync() function queues all the modified block buffers for writing, and returns; it doesn't wait for the actual I/O to take place. Use this function -- or fsync() for a single file -- to ensure consistency of the entire on-disk filesystem with the contents of the in-memory buffer cache.
