|* 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. *|
