Why in a project should I include some *.lib, .h or some other files? And what are these things used for?
.h: header file, its a source file containing declarations (as opposed to .cpp, .cxx, etc. containing implementations),
.lib: static library may contain code or just links to a dynamic library. Either way it’s compiled code that you link with your program. The static library is included in your .exe at link time.
.dll: dynamic library. Just like a static one but you need to deploy it with your .exe file because it’s loaded at run time.
- H Declares the interface to a library – including functions, structures, and constants. Written in the C language.
- LIB Either declares the binary interface to a dynamic library (DLL) or contains the binary code of a library.
- DLL A dynamic library – your application shares these with the system or you use them to keep your code base organized.
- DEF A textual description of functions exported by a DLL.
*.dlb is similar to static library.
