How to check file exists.

Hi All:

To find a file exists using the file name, I have tow routings on UNIX
system.

1. access(2)
2. lstat(2)

This tow function also can do. When the return value is "-1" and errno
is "ENOENT", The file doesn't exist.

**Which one is better?

Thank you very much.
Raymond Shen.

But I only want to know whether the file exists. If fopen success, The file
is open and a system file handler is assigned. I must close the handler.
Consider the performance of the application. I'd like use a lighter routing.


Design issue. Why do you want to know wether the file 'exist' if it's
not to open if in some way ?

Hi, I’ve written a c# program to compact certain msaccess databases. The way this works is to compact say C:\test1.mdb to C:\temp.mdb, then delete C:\test1.mdb and rename C:\temp.mdb as C:\test1.mdb. My problem occurs if there is already a C:\temp.mdb file. I don’t want to just delete this, as it could have been created separately by a user. In my code, I set a constant as follows: private const string tempMdb = @"C:\temp.mdb";

What is the best way to check if a file already exists in the current directory? I saw os.path.isfile(), but I'm not sure if that does more than what I need. I just want to check if a file of a certain name exists before the user creates a new file of that name. Thanks.
