Well, I don''t know if this is the best way but you could do something like this. It''s general and assumes that you do something with the data (copy it to another buffer, transmit it over the internet, process it...) before the next read.

#define BLOCK_SIZE 2048
.
.
.
char sBuffer[BLOCK_SIZE];
int nRet;

FILE *fp = fopen("yourfile.txt", "rb");

while(!feof(fp))
{
nRet = fread(sBuffer, BLOCK_SIZE, sizeof(char), fp);
//Do something with the data in the buffer, you have nRet
//number of characters in there.
}
fclose(fp);
...

I don''t think this is anything new, but this is how I wrote a file transfer program. It was able to transfer a 10Meg file over a network in a couple of seconds(well, maybe a couple more than a couple ). You can play with the block size to see if you can get different results, Leave it a multiple of 2 though.

Also you can check to see what the file size is, allocate a buffer of that size and do one read operation, but something just tells me that I shouldn''t trust reading 10Megs in one call.
But that might just be me.
