Thread: file size detection

Okay, so what is the output from the program I posted?

For example;

Code:

#include <sys/stat.h>
#include <stdio.h>

int main()
{
  struct stat thisInode;

  if ( (stat("/home/dev_x/somefile.zip", &thisInode)) == 0)
    printf("File size in bytes is: %ld\n", thisInode.st_size);
  else
    printf("Could not read file attributes\n");

  return(0);
}

stat() is Posix, which will certainly work in the unix-like environment being discussed here, but as Elysia was kind enough to point out in another thread, Posix is no longer supported by the latest versions of windows, so this code is not portable. Opening the file read-only and seeking to the end is the portable way, if portability is important.
