Predefined macros

AN3350

122/185

Doc ID 018512 Rev 2

Remarks

The compiler implicitly defines this variable at the beginning of each function if the function

refers to __PRETTY_FUNCTION__. This name, function-name, is the same identifier that

appears in source code, not the “mangled” identifier that the compiler and linker use. The

C++ compiler “mangles” a function name by appending extra characters to the function’s

identifier to denote the function’s return type and the types of its parameters.

The ISO/IEC 14882-1998 C++ standard does not specify this symbol.

15.13

__profile__

Preprocessor macro that specifies whether or not the compiler is generating object code for

a profiler.

Syntax

__profile__

Remarks

Defined as 1 when generating object code that works with a profiler. Undefined otherwise.

The ISO standards does not specify this symbol.

15.14

__STDC__

Defined as 1 when compiling ISO/IEC Standard C source code, undefined otherwise.

Syntax

__STDC__

Remarks

The compiler defines this macro as 1 when the compiler’s settings are configured to restrict

the compiler to translate source code that conforms to the ISO/IEC 9899-1990 and ISO/IEC

9899-1999 standards. The compiler does not define this macro otherwise.

15.15

__TIME__

Preprocessor macro defined as a character string representation of the time of compilation.

Syntax

__TIME__

Remarks

The compiler defines this macro as a character string representation of the time of

compilation. The format of this string is

"hh:mm:ss"
