Hi,

my target is too read all Data from a device ((block is more important than char, but best would be a solution that works on both))
Can u tell me wich funktion i should use?
I tried fread...

Solution:



1 #include <fcntl.h>
2 #include <linux/fs.h>
3 #include <stdio.h>
4
5
6 main(int argc, char **argv)

lseek(2)


perhaps lseek isnt the answer to my problem but pv uses it :



77 if (S_ISBLK(sb.st_mode)) {
78 /*
79 * Get the size of block devices by opening

I am using Linux and i use it on an usbstick (/dev/sdb)

sudo ./fs /dev/sdb


cat fs.c


#include <sys/types.h>

I just copied the code out of the man-Page but:



printf("File size: %lld bytes\n", (long long) sb.st_size);


always prints: "0" if u have a block device.

Hi,

i need to get the Size of a file (e.g. ~/files/hallo.txt) and the size of a deivce (e.g. /dev/sdb).


Is it possible to get both with the same functions?
Do i need to use specific...
