How do I find the size of a file?


Use stat(), or fstat() if you have the file open.



These calls fill in a data structure containing all the information
about the file that the system keeps track of; that includes the owner,
group, permissions, size, last access time, last modification time, etc.



The following routine illustrates how to use stat() to get the
file size. 





#include <stdlib.h>


#include <stdio.h>





#include <sys/types.h>


#include <sys/stat.h>





int get_file_size(char *path,off_t *size)


{


  struct stat file_stats;





  if(stat(path,&file_stats))


    return -1;





  *size = file_stats.st_size;


  return 0;


}
