14: Explanation of Function Comments.
15:
16: Every function has a comment preceding it which gives the following
17: information:
18:
19: 1) Function name.
20: 2) A description of what the function does.
21: 3) A list of parameters, each with its type and a short description.
22: 4) A list of return values, each with an explanation of the condition that
23: will cause the function to return that value.
24: 5) A customization section giving tips on how to customize this function
25: for your OLE application.
26: If the customization section says "None" then you may find the function
27: usable as is.
28: If the customization section says "Re-implement" then the function
29: should still serve the same purpose and do what is indicated in the
30: function comment, but will probably need to be re-implemented for
31: your particular application. Any Server Demo code relating to OLE
32: will be useful as a guide in your re-implementation.
33: If the customization section says "Server Demo specific" then the
34: function will probably have no counterpart in your application.
