mkstemp on pre-2.3 Python

[djw]

Hi, c.l.p'ers-

I working on some code that creates a temporary file on Linux. I found some
code that the BDFL posted previously on the newsgroup and adapted it for my
use. I can't get the "pre-2.3" code to work.


try:
    make_temp_file = tempfile.mkstemp # 2.3+
except AttributeError: 
    def make_temp_file( suffix='', prefix='', dir='', text=False ): #pre-2.3
        path = tempfile.mktemp( suffix ) 
        fd = os.open( path, os.O_WRONLY|os.O_CREAT|os.O_EXCL, 0700 )
        os.unlink( path )
        return ( os.fdopen( fd, 'w+b' ), path ) 



Here's the error:

File "utils.py", line 583, in make_temp_file
    return ( os.fdopen( fd, 'w+b' ), path )
OSError: [Errno 22] Invalid argument

Anybody have any ideas on what I am doing wrong?

Thanks,

Don
