DESCRIPTION

13       Data written on the null special file, /dev/null, is discarded.
14
15
16       Reads from a null special file always return 0 bytes.
17
18
19       Mapping  a null special file creates an address reservation of a length
20       equal to the length of the mapping, and rounded up to the nearest  page
21       size  as  returned  by  sysconf(3C).  No  resources are consumed by the
22       reservation. Mappings can be placed in the resulting address range  via
23       subsequent calls to mmap with the -MAP_FIXED option set.
