Macro Value Description
_ _BCOPT_ _ 1 Defined in any compiler that has an optimizer.
_ _BCPLUSPLUS_ _ 0x0560 Defined if you've selected C++ compilation; will increase in later releases.
_ _BORLANDC_ _ 0x0560 Version number.
_ _CDECL_ _ 1 Defined if Calling Convention is set to cdecl; otherwise undefined.
_CHAR_UNSIGNED 1 Defined by default indicating that the default char is unsigned char. Use the -K compiler option to undefine this macro.
_ _CODEGUARD_ _ Defined whenever one of the CodeGuard compiler options is used; otherwise it is undefined.
_ _CONSOLE_ _ 1 When defined, the macro indicates that the program is a console application.
_CPPUNWIND 1 Enable stack unwinding. This is true by default; use -xd- to disable.
_ _cplusplus 1 Defined if in C++ mode; otherwise, undefined.
_ _DATE_ _ String literal Date when processing began on the current file.
_ _DLL_ _ 1 Defined whenever the -WD compiler option is used; otherwise it is undefined.
_ _FILE_ _ String literal Name of the current file being processed.
_ _FLAT_ _ 1 Defined when compiling in 32-bit flat memory model.
_ _FUNC_ _ String literal Name of the current function being processed. More details.
_ _LINE_ _ Decimal constant Number of the current source file line being processed.
_M_IX86 0x12c Always defined. The default value is 300. You can change the value to 400 or 500 by using the /4 or /5 compiler options.
_ _MT_ _ 1 Defined only if the -tWM option is used. It specifies that the multithread library is to be linked.
_ _PASCAL_ _ 1 Defined if Calling Convention is set to Pascal; otherwise undefined.
_ _STDC_ _ 1 Defined if you compile with the -A compiler option; otherwise, it is undefined.
_ _TCPLUSPLUS_ _ 0x0560 Version number.
_ _TEMPLATES_ _ 1 Defined as 1 for C++ files (meaning that templates are supported); otherwise, it is undefined.
_ _TIME_ _ String literal Time when processing began on the current file.
_ _TLS_ _ 1 Thread Local Storage. Always true in C++Builder.
_ _TURBOC_ _ 0x0560 Will increase in later releases.
_WCHAR_T Defined only for C++ programs to indicate that wchar_t is an intrinsically defined data type.
_WCHAR_T_DEFINED Defined only for C++ programs to indicate that wchar_t is an intrinsically defined data type.
_Windows Defined for Windows-only code.
_ _WIN32_ _ 1 Defined for console and GUI applications.
注意，使用时_与_之间没有空格。
