P99_UNROLL #define P99_UNROLL (   MACRO,   N  )    P99_FOR(MACRO, N, P00_SEP, P00_REPEAT, P99_DUPL(N,)) Apply the macro MACRO N times. The macro is called with the numbers 0, ..., N-1 and the N results are separated by a semicolon. In the following example we define an adhoc macro that copies an array element of an array A to the elements of another array B. #define ASIZE 3 double A[] = { P99_DUPL(ASIZE, 1.7) }; double B[] = { P99_DUPL(ASIZE, 371) }; #define COPY_A2B(I) B[I] = A[I] P99_UNROLL(COPY_A2B, ASIZE); This will expand to B[0] = A[0]; B[1] = A[1]; B[2] = A[2]; Observe that the first two ; are inserted automatically as separators by the P99_UNROLL macro. The final one is inserted directly in the program, right after the macro invocation. See also P99_REPEAT for a macro that separates the parts by , P99_SEQ for a similar macro that applies MACRO to a list of items P99_FOR for a more Generic type expressions and Flexible array members utility Remarks argument 0 should correspond to a macro name argument 1 must expand to a decimal number Definition at line 223 of file p99_for.h.
