| |* 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 functions. *| |
