bufferIdLength

bufferIdLength — gives the length of an interpolation buffer.

Syntax

(bufferIdLength id)
    

Parameters

id

The query buffer ID returned from an interpolate command.

Returns

The number (n) of X-Y data pairs in the specified buffer, with the following format:

(bufferIdLength id n)

if successful, otherwise

(error "Invalid buffer id id")

Description

This command determines the exact number of values in the interpolation buffer identified by id.

This command corresponds to the Cogent C API function HI_BufferIDLength, and two dynamic library functions: hist_buffer_id_length and hist_length_buffer.
