Device Drivers & /dev files                                           null(4D)



NAME
       null - the null file, also called the null device

SYNOPSIS
       /dev/null

DESCRIPTION
       Data written on the null special file, /dev/null, is discarded.


       Reads from a null special file always return 0 bytes.


       Mapping  a null special file creates an address reservation of a length
       equal to the length of the mapping, and rounded up to the nearest  page
       size  as  returned  by  sysconf(3C).  No  resources are consumed by the
       reservation. Mappings can be placed in the resulting address range  via
       subsequent calls to mmap with the -MAP_FIXED option set.

FILES
       /dev/null
