NAME
       zero - source of zeroes

DESCRIPTION
       A zero special file is a source of zeroed unnamed memory.


       Reads  from  a zero special file always return a buffer full of zeroes.
       The file is of infinite length.


       Writes to a zero special file are always successful, but the data writ‐
       ten is ignored.


       Mapping  a  zero special file creates a zero-initialized unnamed memory
       object of a length equal to the length of the mapping and rounded up to
       the  nearest  page  size as returned by sysconf. Multiple processes can
       share such a zero special file object provided a common ancestor mapped
       the object MAP_SHARED.

FILES
       /dev/zero
