lt_min

#define lt_min	(		a,
			b
	)

Value:

    __extension__({                \
        __typeof__(a) ___a = (a);  \
        __typeof__(b) ___b = (b);  \
        ___a < ___b ? ___a : ___b; \
    })

This macro uses "statement expressions", which prevent double evaluation in contrast to standard macros.

Note

This uses GCC/Clang compatible extension.
