This module provides generic, low- and high-level interfaces for
creating temporary files and directories. The interfaces listed
as "safe" just below can be used without fear of race conditions.
Those listed as "unsafe" cannot, and are provided for backward
compatibility only.
This module also provides some data items to the user:
TMP_MAX - maximum number of names that will be tried before
giving up.
template - the default prefix for all temporary names.
You may change this to control the default prefix.
tempdir - If this is set to a string before the first use of
any routine from this module, it will be considered as
another candidate location to store temporary files.

This routine should be called exactly once.

trying to create and write to a file in that directory. If this
is successful, the test file is deleted. To prevent denial of

t}nt}t||||�S(sVmkstemp([suffix, [prefix, [dir, [text]]]])
User-callable function to create and return a unique temporary
file. The return value is a pair (fd, name) where fd is the
file descriptor returned by os.open, and name is the filename.
If 'suffix' is specified, the file name will end with that suffix,
otherwise there will be no suffix.
If 'prefix' is specified, the file name will begin with that prefix,
otherwise a default prefix is used.
If 'dir' is specified, the file will be created in that directory,
otherwise a default directory is used.
If 'text' is specified and true, the file is opened in text
mode. Else (the default) the file is opened in binary mode. On
some operating systems, this makes no difference.
The file is readable and writable only by the creating user ID.
If the operating system uses permission bits to indicate whether a
file is executable, the file is executable by no one. The file
descriptor is not inherited by children of this process.
Caller is responsible for deleting the file when done with it.

User-callable function to create and return a unique temporary
directory. The return value is the pathname of the directory.
Arguments are as for mkstemp, except that the 'text' argument is
not accepted.
The directory is readable, writable, and searchable only by the
creating user.
Caller is responsible for deleting the directory when done with it.

User-callable function to return a unique temporary file name. The
file is not created.
Arguments are as for mkstemp, except that the 'text' argument is
not accepted.
This function is unsafe and should not be used. The file name
refers to a file that did not exist at some point, but by the time
you get around to creating it, someone else may have beaten you to
the punch.
