Solution 1

Using C-like API (as you are doing) with ftell: see "function ftell"[^] for sample code.

Solution 3

From here:

http://stackoverflow.com/questions/238603/how-can-i-get-a-files-size-in-c[^]

When using file descriptor.

C++

#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>

struct stat buf;
fstat(fd, &buf);
int size = buf.st_size;
