Questions about data types and converting code from windows to palmOS

[Oz Shalbar]

I have 2 simple questions:

1. Where can I find documentation about simple date types like Word, Uint,
or even PointType,
and what is the big difference between Byte and UInt8 and all the other new
types.

2. What does it take to convet a regular ansi C program that was designed
for windows for example,
to a program that runs on the palm OS. I'm talking about changing all 'int'
to 'Word', every 'malloc' to NewPtr/Handle, 
'char *' to 'CharPtr' etc.
