Thread: rename works intermittently

Hey folks!

Code:

if(!found)
{
        strcpy(LineData[counter2].filename2, LineData[counter].storefilename);
        rewind(p_openfile);
	insertstring();
	counter2++;
	fclose(p_openfile);
        remove(LineData[counter].storefilename);
	rename("tempfile.txt", LineData[counter].storefilename);
}

I have about 80 files that are processed by the above code. In some instances, "tempfile.txt" does not get renamed to "LineData[counter].storefilename".

I can verify that "tempfile.txt" exists, the file "LineData[counter].storefilename" has been deleted, and that "LineData[counter].storefilename" is a valid filename in the structure, using a debugger. So why does rename not work in all instances when it is called?

Thanks in advance.

Make sure that all file handlers and streams that point to LineData[counter].storefilename are closed . . . if you haven't already.

Try rename() on some other files in other programs, and experiment.

check the return value and on failure - exemine errno
