P99_DESIGNATED #define P99_DESIGNATED (   VAR,   ...  )    { P00_DESIGNATED(VAR, P99_NARG(__VA_ARGS__), __VA_ARGS__) } Construct a designated initializer by copying fields of VAR. The argument list must be composed of designators, something like struct toto { int a; int b; } A = { .a = 9, .b = 7 }; struct toto B = P99_DESIGNATED(A, .b); double C[4] = { 1, 2, 3, 4 }; double D[4] = P99_DESIGNATED(C, [0], [2]); So here B.b is initialized with the value of A.b and B.a, since .a is not in the list, is initialized by 0. Likewise D gets copies of C[0] and C[2] and the other fields are initialized to 0.
