-doesn't return a value.
-.Sh COMPATIBILITY
-.Fn putenv
-no longer copies its input buffer.
-This often appears in crash logs as a crash in
-.Fn getenv .
-Avoid passing local buffers or freeing the memory
-that is passed to
-.Fn putenv .
-Use
-.Fn setenv ,  
-which still makes an internal copy of its buffers.
-.Pp
-.Fn unsetenv
-no longer parses the variable name;
-e.g., unsetenv ("FOO=BAR") no longer works.
-Use unsetenv("FOO").
-.Fn unsetenv
-also now returns a status value and will set
-.Va errno
-to EINVAL if
-.Fa name
-is not a defined environment variable.
