CONST_ATTRIBUTE Top

Standardization of the const compiler attribute

#if ( defined( __GNUC__ ) && ( ( __GNUC__ >= 4 ) || ( ( __GNUC__ == 3 ) && ( __GNUC_MINOR__ >= 1 ) ) ) ) || defined( __clang__ ) #define CONST_ATTRIBUTE __attribute__( ( const ) ) #else #define CONST_ATTRIBUTE #endif

Discussion

Not all compiler support this attribute, so it may be defined to nothing.
