NAME
       putenv - change or add an environment variable

SYNOPSIS
       #include 

       int putenv(char *string);

DESCRIPTION
       The  putenv()  function  adds or changes the value of environment vari -
       ables.  The argument string is of the form name=value.   If  name  does
       not already exist in the environment, then string is added to the envi -
       ronment.  If name does exist, then the value of name in the environment
       is  changed  to value.  The string pointed to by string becomes part of
       the environment, so altering the string changes the environment.
