Re: fscanf hangs

I am using MS Visual C++ 6.0 on Windows XP 5.1 (SP2).

I am not sure if this is a C, C++ or MS issue but fscanf has been
randomly hanging on me. I make the call hundreds, if not thousands,
of times but it hangs in different places with the same data. The
offending code follows.

ReadFile(char *csFileName)
{
        float fFloat1, fFloat2;
        long lLong1, lLong2, lNum, lLastX = iColumns-1, lLastY =iRows-1;
        int iRead;
                FILE *fpInFile;

                if ((fpInFile= fopen(csFileName, "r")) == NULL) return
ErrorOpeningFile(csFileName);

        do
        {
                                // It randomly hangs on the followinf
line
                iRead=fscanf(fpInFile, "%d%d%f%f%d", &lLong1, &lLong2, &fFloat1,
&fFloat2, &lNum);
                if (iRead==0 || iRead==EOF) break;
        } while (lX < lLastX || lY < lLastY);

}

I am wondering if I should just do binary reading so as to have more
control over what is going on.

Many thanks in advance for any assistance,
Peter.
