Due to disk caching interactions within the system, theFlushFileBuffersfunction can be inefficient when used after every write to a disk drive device when many writes are being performed separately. If an application is performing multiple writes to disk and also needs to ensure critical data is...
The FlushFileBuffers function clears the buffers for the specified file and causes all buffered data to be written to the file. BOOL FlushFileBuffers( HANDLE hFile // open handle to file whose buffers are to be flushed ); Parameters h...
