Identifier: scratch

Type

string

Description

The name of a scratch directory. There is one scratch directory permitted per session. The name of this directory is constructed from the external environment variable MXTEMPDIR (or /usr/tmp if MXTEMPDIR is undefined) and the session process number. It is guaranteed to be unique. The value of this string variable is maintained by the system and cannot be redefined.

The user is free to create and delete files within the scratch directory, but at the end of a session the directory and its contents are erased, unless the session was terminated abnormally.
