MACRO_OVERLOAD

#define MACRO_OVERLOAD	(		prefix,
			... )

Value:

PREPROCESSOR_APPEND_VA_ARG_COUNT(prefix, __VA_ARGS__)(__VA_ARGS__)

Implement preprocessor function overloading based on argument count for a set of macros following a distinct convention. Individual overloads must have a trailing number corresponding to the number of arguments they accept.

For example:

#define FOO_3(a, b, c) a##b##c
#define FOO_2(a, b)    a##b
#define FOO_1(a)       a
 
#define FOO(...) MACRO_OVERLOAD(FOO_, __VA_ARGS__)
 
FOO(1) // -> 1
FOO(1, 2) // -> 12
FOO(1, 2, 3) // -> 123
