|
Explanation of Function Comments.
|
|
|
|
Every function has a comment preceding it which gives the following
|
|
information:
|
|
|
|
1) Function name.
|
|
2) A description of what the function does.
|
|
3) A list of parameters, each with its type and a short description.
|
|
4) A list of return values, each with an explanation of the condition that
|
|
will cause the function to return that value.
|
|
5) A customization section giving tips on how to customize this function
|
|
for your OLE application.
|
|
If the customization section says "None" then you may find the function
|
|
usable as is.
|
|
If the customization section says "Re-implement" then the function
|
|
should still serve the same purpose and do what is indicated in the
|
|
function comment, but will probably need to be re-implemented for
|
|
your particular application. Any Server Demo code relating to OLE
|
|
will be useful as a guide in your re-implementation.
|
|
If the customization section says "Server Demo specific" then the
|
|
function will probably have no counterpart in your application.
