Re: fread() function and unsigned integers, words and dwords

["Ben Humphrey" <benjina@mindspring.com>]

here is how fread works:

fread( the buffer to hold what you are reading in,
           the size of the data you are reading in,
           the amount of the size you just specified,
           the file pointer);

here is an example

fread(&buffer, sizeof(DWORD), 10, filePointer);

That would read in 10 DWORD's.  if you want integer, say sizeof(integer)....
get it?

fread is a great function.

the file pointer is the variable "FILE *filePointer" that you declare if you
are reading from a file.

Let me know if you need more explaining and I would be happy to write a
SIMPLE example.

i am good at that :)
