Sparse Matrix mkl_?csrmultd problem

Hello,

I want to use the mkl_?csrmultd to do 2 matrix product and the output is a dense matrix.

But i am confused when i read the manual, The ldc (leading dimension of dense matrix C) is a output  parameters( not a input parameter as usual ?), and the length of ib is m+1. The definition of ia is also very different with other sparse matrix routines, because the length is not m+1. 

Is there any problem about this part?

Any help and comment will be appreciated.
