Well-Connected
Real-Time
General Principles




Unicode-Only
Focus on “Client-side” support
No Security
No “Frills”



Few helpers (ZeroMemory)
Cut Win16 functions
Leave one function when Win32 has 2+ ways
to do something


TextOut versus ExtTextOut
MoveToEx/LineTo versus Polyline
Windows NT Supports
Both Unicode And Ansi
APP.EXE
MessageBoxA
USER32.DLL
MessageBoxW
MessageBoxW
Unicode
Compiler Support

ANSI characters and strings




Unicode characters and strings




‘H’
“Hello Unicode”
==> Store as ‘char’ or ‘unsigned char’
L’H’
L”Hello Unicode”
==> Store as ‘short’ or ‘unsigned short’
Bi-modal (_UNICODE)


TEXT(‘H’)
TEXT(“Hello Unicode”)
Unicode
Data Types

ANSI



Unicode



CHAR – resolves to char
LPSTR – resolves to char *
WCHAR – resolves to unsigned short
LPWSTR – resolves to unsigned short *
Bi-Modal (_UNICODE)


TCHAR – resolves to char or
unsigned short
LPTSTR – resolves to char *
or unsigned short *
Unicode
C-Runtime Functions

ANSI




Unicode




strlen() – query length
strcpy() – copy string
strcat() – concatenate string
wcslen() – query length
wcscpy() – copy string
wcscat() – concatenate string
Bi-Modal (_UNICODE)



_tcslen() – query length
_tcscpy() – copy string
_tcscat() – concatenate string
Unicode Conversion

Functions



mbstowcs – To Unicode ("Wide-character string")
wcstombs – From Unicode
Establish a clear boundary between Unicode and
Non-Unicode Functions
The Outside World
