When two or more source files include the same header, the exported inline functions end up duplicated in both object files. When linking these objects together in the final DLL, the linker would give an error because of the multiple definitions. To avoid this, each exported inline function is placed in a separate section, identified by the COMDAT name. When the linker sees two or more sections with the same COMDAT name, it can safely keep one of them and discard the rest.
