c file size
If you use :
/**
Pay attention to return type!
ftell returns long, which can only be used for files under 2GB.
**/
fseek(f, 0, SEEK_END); // seek to end of file
size = ftell(f); // get current file pointer
fseek(f, 0, SEEK_SET); // seek back to beginning of file
// If u want to get file of large size, use stat() instead
struct stat buf;
if(stat(filename, &buf) == -1){
return -1;
}
return (ssize_t)buf.st_size;
