GNU Attributes
Go Up to C++ Specifics Index
C++Builder supports the following GNU attributes:
- aligned (ALIGNMENT) [documented below]
- cdecl
- stdcall
- dllimport
- dllexport
- alias ("name")
- const
- constructor
- destructor
- eightbit_data
- exception (EXCEPT-FUNC [, EXCEPT-ARG])
- format (ARCHETYPE, STRING-INDEX, FIRST-TO-CHECK)
- format_arg (STRING-INDEX)
- function_vector
- interrupt
- interrupt_handler
- longcall
- model (MODEL-NAME)
- noreturn
- regparm (NUMBER)
- section ("section-name")
- tiny_data
- unused
- weak
Note: To use the GNU attributes, compile the C++ code with the
-AG
flag. See BCC32.EXE, the C++ 32-bit Command-Line Compiler and C++ Compiler (language compliance).
aligned (ALIGNMENT)
Use this attribute to force the minimum alignment of a specific data block.
Example:
// flags: -AG
struct Coordinate
{
int x, y, z;
};
Coordinate c __attribute__((aligned (8)));
Note: To set the general data alignment, open Project Options > C++ Compiler > General Compilation > Data Alignment. See the compiler option
-a
.
