Error on file open: File exists

Question

The return value of an open() was -1 and on trying to find the error using perror() the output was "File exists".

How do I find the error or the reason for the file not opening.

Well, it seems you've found the reason why it fails, so... what's exactly your question? — psycho, Sep 12 '11 at 16:02
Please post the code you use in your `open` call. Chances are you're using options incompatible with opening an existing file. — Mat, Sep 12 '11 at 16:02
Please post the call to `open()`, or this question will quickly be closed. — Tim Post, Sep 12 '11 at 16:34

Looks like

EEXIST
pathname already exists and O_CREAT and O_EXCL were used.

You probably would have given the macro with the quotes as described below:

fd = open(filename,"O_RDONLY" );

It should be fd = open(filename,O_RDONLY); without quotes.

-1: This is pure guessing - and the appropriate code you suggest might even not compile. – Andreas Florath Apr 18 '12 at 06:14
