| michael@0 | 11 | * Memory mapped file wrappers for use by the ICU Data Implementation |
| michael@0 | 12 | * |
| michael@0 | 13 | * Porting note: The implementation of these functions is very platform specific. |
| michael@0 | 14 | * Not all platforms can do real memory mapping. Those that can't |
| michael@0 | 15 | * still must implement these functions, getting the data into memory using |
| michael@0 | 16 | * whatever means are available. |
| michael@0 | 17 | * |
| michael@0 | 18 | * These functions are part of the ICU internal implementation, and |
| michael@0 | 19 | * are not inteded to be used directly by applications. |
