Microsoft MFC macro naming rules

Name	Type
_ Afxdll	Unique dynamic connection library (DLL) version
_ Alpha	Compile only the DEC Alpha processor
_ Debug	Including debugging versions for Diagnosis
_ MBCS	Compile multi-byte character sets
_ Unicode	Open Unicode in an application
Afxapi	Functions provided by MFC
Callback	Function called back by pointer

Library identifier name Method

Identifier	Value and meaning
U	ANSI (n) or Unicode (u)
D	Debug or release: D = debug; ignore the identifier as release.

Static library version naming rules

Library	Description
Nafxcwd. Lib	Debug version: MFC static Connection Library
Nafxcw. Lib	Release Version: MFC static Connection Library
Uafxcwd. Lib	Debug version: provides a static MFC Connection Library with Unicode support
Uafxcw. Lib	Release Version: static Connection Library of MFC with Unicode support

Dynamic Connection Library naming rules

Name	Type
_ Afxdll	Unique dynamic connection library (DLL) version
Winapi	Functions provided by Windows

New naming rules in windows. h

Type	Definition description
Winapi	Use the far Pascal position in the API declaration. If you are writing a DLL with an export API population, you can use this type in your own API.
Callback	The position of the far Pascal used in the application call-back routine, such as the window and dialog box
Lpcstr	It is the same as lpstr, but lpcstr is used for read-only string pointers. Its definition is similar to (const char far *)
Uint	The portable unsigned integer type. Its size is determined by the host environment (32-bit for Windows NT and Windows 9x). It is a synonym for unsigned Int.
Lresult	Type of window program return value
Lparam	Declares the type used by lparam. lparam is the fourth parameter of the window program.
Wparam	Declares the type used by wparam. wparam is the third parameter of the window program.
Lpvoid	The pointer type, which is the same as (void *) and can be used to replace lpstr.
