Re: [Dev-C++] libraries and include files

If you include conio.h, no declared functions will be included in your
program.

However, when your program uses one or more variables or functions from a
library, the linker will extract the needed object files from the relevant
library.

Since a library is just a single file containing a collection of object
files, the library creator will decide what granularity of functions the
linker may select. If all conio functions were compiled from a single
source file, all conion functions will be located in the same object
file within the library. Then, the linker is forced to include all conio
functions - even the unused ones.

This is one of the reasons why source code to runtime libraries normally
contains thousands and thousands of small source files. Each source file
just contains one or two functions, to give the linker a possibility of
being selective about what to include.
