|---|
| 11 | |* This file is important because different host OS's define different macros,*| |
|---|
| 12 | |* which makes portability tough. This file exports the following *| |

| 15 | |* [u]int(32|64)_t : typedefs for signed and unsigned 32/64 bit system types*| |
|---|
| 16 | |* [U]INT(8|16|32|64)_(MIN|MAX) : Constants for the min and max values. *| |
