Compatibility: 1.0+

Expects: AH    0DH

Returns: none

Info: Flushes all file buffers.

This does NOT update file length in a directory.  To ensure a

file's length is correctly recorded, close the file via Fn 10H or

3eH.

Notes:   All MS-DOS tools that buffer I/O data will honor this function,

including the SmartDrv disk cache and caching performed by

DoubleSpace.  For instance, if you want to avoid having

Smartdrv perform its periodic disk output during a time-

critical program function, use Fn 0dH before starting that

function.

  Control does not return until all buffers have been flushed.

  The default INT 23H Ctrl+Break handler calls this function when

DOS detects Ctrl+Break or Ctrl+C.
