1.        * mode_t shall be an integer type.
   
2. 
   
3.         * nlink_t, uid_t, gid_t, and id_t shall be integer types.
   
4. 
   
5.         * blkcnt_t and off_t shall be signed integer types.
   
6. 
   
7.         * fsblkcnt_t, fsfilcnt_t, and ino_t shall be defined as unsigned integer types.
   
8. 
   
9.         * size_t shall be an unsigned integer type.
   
10. 
    
11.         * blksize_t, pid_t, and ssize_t shall be signed integer types.
    
12. 
    
13.         * time_t and clock_t shall be integer or real-floating types.
    
14. 
    
15.        The  type ssize_t shall be capable of storing values at least in the range [-1, {SSIZE_MAX}].  The type useconds_t shall be an unsigned inte-
    
16.        ger type capable of storing values at least in the range [0, 1000000]. The type suseconds_t shall be a signed integer type capable of storing
    
17.        values at least in the range [-1, 1000000].
    
18. 
    
19.        The  implementation shall support one or more programming environments in which the widths of blksize_t, pid_t, size_t, ssize_t, suseconds_t,
    
20.        and useconds_t are no greater than the width of type long. The names of these programming environments can be obtained  using  the  confstr()
    
21.        function or the getconf utility.
