`hist_buffer_id_destroy`

hist_buffer_id_destroy — destroys an interpolation query buffer.

Syntax

hist_buffer_id_destroy(hist_task, queryid)

Parameters

hist_task

The task object corresponding to the Cascade Historian. A task object is created by a call to the Gamma function locate_task, as follows:

hist_task = locate_task ("tfrc/histdb", nil);

queryid

The reference number for the result of a query made on the Cascade Historian using the hist_interpolate function or the interpolate command.

Returns

t (true) if the transformation was performed with no errors, otherwise nil.

Description

This function destroys the temporary internal buffer associated with an interpolation request. The memory allocated by an interpolation request can be very large, and will persist until it is explicitly destroyed.

This function corresponds to the bufferIdDestroy command and the Cogent C API function HI_BufferIDDestroy.
