FLUSH
The FLUSH procedure causes all buffered output on the specified file units to be written. IDL uses buffered output for reasons of efficiency. This buffering leads to rare occasions where a program needs to be certain that output data are not waiting in a buffer, but have actually been output.
Syntax
FLUSH, Unit1, ..., Unitn
Arguments
Uniti
The file units (logical unit numbers) to flush.
