LPCTSTR和LPTSTR和char *
"LP"前缀是历史遗留的,在Win32下就是 P ,代表指针的含义。
"C"代表const
"T"的含义就是如果定义了UNICODE,它就是宽字符版本,否则就是Ansi版本。
完整定义如下:
//Unicode 版本
typedef wchar_t WCHAR;
typedef WCHAR *PWCHAR;
typedef WCHAR *LPWCH, *PWCH;
typedef CONST WCHAR *LPCWCH, *PCWCH;
typedef WCHAR *NWPSTR;
typedef WCHAR *LPWSTR, *PWSTR;
typedef WCHAR UNALIGNED *LPUWSTR, *PUWSTR;
typedef CONST WCHAR *LPCWSTR, *PCWSTR;
typedef CONST WCHAR UNALIGNED *LPCUWSTR, *PCUWSTR;
// Ansi版本
typedef CHAR *PCHAR;
typedef CHAR *LPCH, *PCH;
typedef CONST CHAR *LPCCH, *PCCH;
typedef CHAR *NPSTR;
typedef CHAR *LPSTR, *PSTR;
typedef CONST CHAR *LPCSTR, *PCSTR;
#ifdef UNICODE
typedef WCHAR TCHAR, *PTCHAR;
typedef WCHAR TBYTE , *PTBYTE ;
typedef LPWSTR LPTCH, PTCH;
typedef LPWSTR PTSTR, LPTSTR;
typedef LPCWSTR PCTSTR, LPCTSTR;
typedef LPUWSTR PUTSTR, LPUTSTR;
typedef LPCUWSTR PCUTSTR, LPCUTSTR;
typedef LPWSTR LP;
#else
