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