/*
   int stat ( const char *file,  struct stat *buf) 
   Get file attributes for FILE and put them in BUF.  

   int fstat ( int fd, struct stat *buf )
   Get file attributes for the file, device, pipe, or socket
   that file descriptor FD is open on and put them in BUF. 

   int lstat ( const char *file, struct stat *buf) 
   Get file attributes about FILE and put them in BUF.
   If FILE is a symbolic link, do not follow it.  

*/

/*
   int fstatat (int fd, const char *file, struct stat *buf, int flag )

   Similar to stat, get the attributes for FILE and put them in BUF.
   Relative path names are interpreted relative to FD unless FD is
   AT_FDCWD. 

   If fstatat() is passed the special value AT_FDCWD in the fd parameter, 
   the current working directory shall be used and the behavior shall be 
   identical to a call to stat() or lstat() respectively, depending on  
   whether or not the AT_SYMLINK_NOFOLLOW bit is set in flag.
