putenv:
Synopsis: Change or add a value to the environment
Syntax: putenv ( STRING )
Description:
putenv takes a single argument, STRING, of the form:
"NAME=VALUE"
putenv make the value of the environment variable NAME equal
to VALUE by altering an existing variable or creating a new
one.
Exactly how putenv behaves is depends upon the underlying
operating system implementation.
On most Unix systems putenv will return non-zero if an error
occurred, and zero otherwise.
