save the content of a memory block to a local file.

1. if ipFilePath already exist, check iFlag. If iFlag != 0, return failure. Otherwise, append ipData to the end of the file.
2. Since mmap requires the offset to be aligned at page size, we need return both the original mapped filed memory address and the adjusted memory address.
