| // This file contains definitions to figure out the size of _HOST_ data types. |
| // This file is important because different host OS's define different macros, |
| // which makes portability tough. This file exports the following definitions: |
| // |
| // [u]int(32|64)_t : typedefs for signed and unsigned 32/64 bit system types |
| // [U]INT(8|16|32|64)_(MIN|MAX) : Constants for the min and max values. |
| // |
| // No library is required when using these functinons. |
