DESCRIPTION

14       mmap_private  opens  filename  for  reading and writing, maps the whole
15       file into memory, closes the file, writes the length  of  the  file  to
16       filesize and returns a pointer to the mapped file.
17
18       The  file  is  mapped copy-on-write.  Changes done to the mapped region
19       will not be written to disk.
20
21       The file is unmapped by the operating system if the process terminates.
22       It can also be manually unmapped by calling munmap from <sys/mman.h>.
23
24       If the file could not be opened or mapped, (void*)0 is returned.
