Syntax

hist_flush (hist_task[, pattern])

Parameters

hist_task: The task object corresponding to the Cascade Historian. See locate_task in the Gamma manual.
pattern: The name of one or more (using a globbing pattern) histories to be acted upon. When this parameter is not specified, the default is *, to include all histories.

Returns

t (true) if successful. Otherwise returns nil and sets _last_error_ to the error string returned by the Cascade Historian.

Description

This function removes the data for the specified history or histories from the buffer and writes them to the associated files. If no pattern is specified, all buffers are flushed to file.

This function corresponds to the flush command, and the Cogent C API function HI_Flush.
