======================================================================== DYNAMIC LINK LIBRARY : macwireless ======================================================================== AppWizard has created this macwireless DLL for you. This file contains a summary of what you will find in each of the files that make up your macwireless application. macwireless.dsp This file (the project file) contains information at the project level and is used to build a single project or subproject. Other users can share the project (.dsp) file, but they should export the makefiles locally. macwireless.cpp This is the main DLL source file. When created, this DLL does not export any symbols. As a result, it will not produce a .lib file when it is built. If you wish this project to be a project dependency of some other project, you will either need to add code to export some symbols from the DLL so that an export library will be produced, or you can check the "doesn't produce lib" checkbox in the Linker settings page for this project. ///////////////////////////////////////////////////////////////////////////// Other standard files: StdAfx.h, StdAfx.cpp These files are used to build a precompiled header (PCH) file named macwireless.pch and a precompiled types file named StdAfx.obj. ///////////////////////////////////////////////////////////////////////////// Other notes: AppWizard uses "TODO:" to indicate parts of the source code you should add to or customize. /////////////////////////////////////////////////////////////////////////////
