Description Russell Francis 2003-12-24 14:00:32 UTC 
The getenv(3) manpage doesn't state that the return value should not be freed.  This has the potential of creating confusion for developers who may be tempted to free the value returned from getenv.

Attached is a short diff which clarifies description of the return value from getenv in the manpage.

How-To-Repeat: Type this

#man 3 getenv

Revision 1.15 discussed the return value, so I have committed 
a different fix explaining that applications should not modify 
the return value.  Thanks for the submission!
