34 | Revision : $Version$ | |
35 | Description: provides a set of routines for maintaining an | |
36 | efficient mechanism to group opaque (or pointer) | |
37 | data structures together. Internally the | |
38 | entities are grouped together using a binary | |
39 | tree. It does not use Storage - and instead | |
40 | uses malloc, free from libc as Storage uses the | |
41 | module to detect erroneous deallocations. | |
