My program can't read :(

[wossname]

I am using this code to try to read an entire file into an array

#include <fstream> 
typedef unsigned long int ULI;
.
.
.
ULI M[numElements]; //creates an unsigned long int array, numElements is sufficient to hold the entire file

for(i=0;i<numElements;i++)
{ M[i]=0; }

//open the file
ifstream fin(filename,ios::binary);
//read it into M[]
fin.read((ULI *) &M, flen);
fin.close();

But when I tested it, by printing the contents of M[] to the screen, I just get zeroes for all elements.

What's wrong with the code? It all compiles without any errors. This is in DOS by the way, DJGPP compiler.

You need to go through each byte of the file and place that in an element of M. Why are you using unsigned long's?

Cos I'm a perverse son of a b****. Well, the algorithm that I'm ripping off uses them. Its part of a file validation signature that I'm building on.

I think the theme of this thread will be engraved on my gravestone when I die. It'll be that long before anyone works out how to do it let alone me!

Ok, ok I give up. How do i read the data into a Char? I'll just have to get it in lumps of four bytes and left shift them into place.

Not very elegant though.
