Little Endian From Binary File?

[rzumbado]

Hi there all!

I'm looking for a way to get an int value from a binary file. So lets say i have this file "myfile.dat" where from my PC i stored a lot of stuff...
Now i need to read that file from my IPhone and show the data...

on the "myfile.dat" i have this (binary and all ints are little endian):
0-12: A signature string
13-16: An int number (note that length = 4)

So using NSData i know i can read from pos 13 to pos 16 and get those bytes... i can get the first 0-12 string correctly, but i cannot read pos 13-16 and convert it to an int value in Obj-C.... ;(

I have something like:

unsigned char bytes[length];
[_data getBytes:bytes range:NSMakeRange(offset, length)];
int32_t elem = OSReadLittleInt32(bytes, 0);

Now, im a newbie when it comes to Obj-C and C/C++... all my life i have been working with C# (sad)...

Can anyone help? THANKS IN ADVANCE!
