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