The Straightforward Part —You can use the following items of information as
you find them in the manual, with no change:
•
The XView procedure names
• The XView object names
• The XView object data types (except Boolean , see the following section)
The More Complex Parts —You must make the following changes:
•
Any elementary C data type used must be converted to the corresponding
Pascal data type.
•
Any C procedure that returns something must be invoked in Pascal as a
function; otherwise, it must be invoked as a procedure.
•
The XView type Boolean must be converted to the Pascal type, boolean .
Table 10-1 shows you how to convert C declarations to Pascal.
