Thread: Read a file in windows using c code from a linux machine

I have a win7 PC with a folder "c:\temp" set-up for sharing. I see State: Shared below the folder. I have a small RISC machine running linux. I wrote a c program on the linus machine to access the win7 folder. The RISC and win7 PC are connected using a cross-over cable.

In my code, I have the following line:

fp = fopen("////169.254.5.155//temp//test1.txt", "w+");

followed by a fprintf statement.

When I run the c program on the linux machine, I get Segmentation fault. The IP you see is that of the win7 PC.
Please Help.

You presumably mean all of those forward slashes to be backslashes. Alternatively, you could just use half as many forward slashes.

But I still don't think it will work.

I just tried
fp = fopen("\\169.254.5.155\temp\test1.txt", "w+");
and I have a file on my linux machine named
\169.254.5.155\temp\test1.txt
and nothing in c:\temp on the win7 machine

I assume you mean those to be forward slashes this time! You either need to use single forward slashes: "//1.2.3.4/one/two/three" or double backslashes "\\\\1.2.3.4\\one\\two\\three". And the first one being doubled ("//" or "\\\\") probably doesn't have any effect (on linux, at least).

Anyway, I don't know how to do what you want.

I doubt it's just a matter of sticking the IP address in front of the file name like that ... although it could be, I guess. More likely there's some directory (like /dev or a subdirectory of it) on the linux machine where the IP exists. So it would be something like "/dev/ip/1.2.3.4/temp/test1.txt". But I'm just making that up.

I have tried many combinations.
