|
|
* types and constants
|
|

|
|
*
|
|
* The following platform independent data types and corresponding
|
|
* preprocessor (#define) constants are defined:
|
|
*
|
|
* defined type meaning corresponding constants
|
|
* ----------------------------------------------------------
|
|
* Char character (none)
|
|
* Bool boolean true, false
|
|
* Word8 8-bit signed minWord8, maxWord8
|
|
* UWord8 8-bit unsigned minUWord8, maxUWord8
|
|
* Word16 16-bit signed minWord16, maxWord16
|
|
* UWord16 16-bit unsigned minUWord16, maxUWord16
|
|
* Word32 32-bit signed minWord32, maxWord32
|
|
* UWord32 32-bit unsigned minUWord32, maxUWord32
|
|
* Float floating point minFloat, maxFloat
|
|
*
|
|
*
|
|
* The following compile switches are #defined:
|
|
*
|
|
* PLATFORM string indicating platform progam is compiled on
|
|
* possible values: "OSF", "PC", "SUN"
|
|
*
|
|
* OSF only defined if the current platform is an Alpha
|
|
* PC only defined if the current platform is a PC
|
|
* SUN only defined if the current platform is a Sun
|
|
*
|
|
* LSBFIRST is defined if the byte order on this platform is
|
|
* "least significant byte first" -> defined on DEC Alpha
|
|
* and PC, undefined on Sun
