It tells me that it ignores unused function. Should I use all the functions of a library that I include into my project if I need only one? IMO, if I don't use a function then there is no need neither to use it nor mention about all the functions of the library module. Explain this, please, to Pascal/Java follower.
Creating a library is simple. Creating a good, useful library is more difficult. Refer to the following knowledgebase article: http://www.keil.com/support/docs/2182.htm. Jon
