Detailed Description

Mostly this is a concession to the idiosyncracies of Visual C++, which still as of its 2017 version is unable to count __VA_ARGS__ as n arguments, and instead counts it as 1. Mostly. But as David Wheeler remarked, one extra level of indirection is the solution to any computer science problem.

Macro Definition Documentation

◆ CPPX_INVOKE_MACRO

#define CPPX_INVOKE_MACRO	(	m,
		arglist
	)

Invokes the specified macro with the specified arguments list.

Parameters

m	The name of a macro to invoke.
arglist	A parenthesized list of arguments. Can be empty.

Definition at line 17 of file macro-invoke_macro.hpp.

◆ CPPX_INVOKE_MACRO_B

#define CPPX_INVOKE_MACRO_B	(	m,
		arglist
	)

Invokes the specified macro with the specified arguments list.

Parameters

m	The name of a macro to invoke.
arglist	A parenthesized list of arguments. Can be empty.

The only difference between CPPX_INVOKE_MACRO and CPPX_INVOKE_MACRO_B is that they're different macros. One may have to use both in order to guarantee macro expansion in certain (not very well defined) situations. E.g. see <cppx-core/meta-macro/macro-apply.hpp>.
