environ -- C Language

Process environment

extern char **environ;

environ is  an array of strings,  called the environment of  a process.  By
convention, each string has the form

    name=value

Normally, each process inherits the environment of its parent process.  The
shell sh and  various forms of exec can change  the environment.  The shell
adds the  name and value  of each shell  variable marked for  export to the
environment of  subsequent commands.  The  shell adds assignments  given on
the  same line  as a  command to  the environment  of the  command, without
affecting subsequent commands.
