18 * This software can be used to read files produced by the RRDTool

20 *
21 * Limitations:
22 *
23 * This version of the module assumes RRD files created on linux
24 * with intel architecture and supports both 32 and 64 bit CPUs.
25 * All integers in RRD files are suppoes to fit in 32bit values.
26 *
27 * Only versions 3 and 4 of the RRD archive are supported.
28 *
29 * Only AVERAGE,MAXIMUM,MINIMUM and LAST consolidation functions are
30 * supported. For all others, the behaviour is at the moment undefined.

39 * getByteAt(idx) - Return a 8 bit unsigned integer at offset idx
40 * getLongAt(idx) - Return a 32 bit unsigned integer at offset idx
41 * getDoubleAt(idx) - Return a double float at offset idx
42 * getFastDoubleAt(idx) - Similar to getDoubleAt but with less precision
43 * getCStringAt(idx,maxsize) - Return a string of at most maxsize characters
