This module generates temporary file names. It is not Unix specific, but it may require some help on non-Unix systems.
Note: the modules does not create temporary files, nor does it automatically remove them when the current process exits or dies.
The module defines a single user-callable function:
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.
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), or tmp (all
other systems).
Warning: if a Unix process uses mktemp(), then
calls fork() and both parent and child continue to use
mktemp(), the processes will generate conflicting temporary
names. To resolve this, the child process should assign None to
template, to force recomputing the default on the next call
to mktemp().
