14 * Description: |
|
15 * This maps Symbian OS memory management onto Icu Umemory functions |
|
16 * Memory is allocated from the shaper internal heap, which has been saved in the TLS. |
|
17 * If there is no memory available these memory functions leave, this is caught in the shaper wrapper. |
|
18 * For debugging there is an alternative set of functions which log memory allocations |
|
