This module generates temporary file names. It is not Unix specific, but it may require some help on non-Unix systems.
The module defines the following user-callable functions:
The mode parameter defaults to
'w+b' so that the file
created can be read and written without being closed. Binary mode is
used so that it behaves consistently on all platforms without regard
for the data that is stored. bufsize defaults to
meaning that the operating system default is used. suffix is
passed to mktemp().
The module uses two global variables that tell it how to construct a temporary name. The caller may assign values to them; by default they are initialized at the first call to mktemp().
None, this variable defines the directory in which filenames returned by mktemp() reside. The default is taken from the environment variable TMPDIR; if this is not set, either /usr/tmp is used (on Unix), or the current working directory (all other systems). No check is made to see whether its value is valid.
templatevariable directly. New in version 1.5.2.
When set to a value other than
None, this variable defines the
prefix of the final component of the filenames returned by
mktemp(). A string of decimal digits is added to generate
unique filenames. The default is either @pid. where
pid is the current process ID (on Unix),
~pid- on Windows NT, Python-Tmp- on
MacOS, or tmp (all other systems).
Older versions of this module used to require that
None after a call to os.fork(); this has not
been necessary since version 1.5.2.
