hist_enable (hist_task[, pattern])
The task object corresponding to the Cascade Historian. See locate_task in the Gamma manual.
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.
t (true) if successful. Otherwise returns nil and sets _last_error_ to the error string returned by the Cascade Historian.
This function reverses the effect of a previous disable, hist_disable, or HI_Disable call, so that new data values will be accepted and logged.
This function corresponds to the enable command, and the Cogent C API function HI_Enable.
