ARGUMENTS N (input) On entry, N specifies the number of elements in the vector. If N <= 0 then the function returns the value DB+QC. Unchanged on exit. DB (input) On entry, the constant that is added to the dot product before the result is returned. Unchanged on exit. QC (input/output) On entry, the extended precision constant to be added to the dot product. On exit, the extended precision result. DX (input) On entry, the incremented array DX must contain the vector x. Unchanged on exit. INCX (input) On entry, INCX specifies the increment for the elements of DX. Unchanged on exit. DY (input) On entry, the incremented array DY must contain the vector y. Unchanged on exit. INCY (input) On entry, INCY specifies the increment for the elements of DY. Unchanged on exit.
