15.6

__FILE__

Preprocessor macro of the name of the source code file being compiled.

Syntax

__FILE__

Remarks

The compiler defines this macro as a character string literal value of the name of the file

being compiled, or the name specified in the last instance of a #line directive.

15.7

__func__

Predefined variable of the name of the function being compiled.

Prototype

static const char __func__[] = "function-name";

Remarks

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

refers to __func__. The character string contained by this array, function-name, is the

name of the function being compiled.

This implicit variable is undefined outside of a function body. This variable is also undefined

when C99 (ISO/IEC 9899-1999) or GCC (GNU Compiler Collection) extension settings are

off.

15.8

__FUNCTION__

Predefined variable of the name of the function being compiled.

Prototype

static const char __FUNCTION__[] = "function-name";

Remarks

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

refers to __FUNCTION__. The character string contained by this array, function-name, is the

name of the function being compiled.

This implicit variable is undefined outside of a function body.

15.9

__ide_target()
