QR Factorization

I'm trying to use ACML LAPACK/BLAS routines. I specifically use C fortran interfaces (e.g. function names end with underscores).

The problem I face is that ACML method signatures differ from the LAPACK/BLAS standard. For instance, in LAPACK dormqr take 13 parameters, while the ACML version requires 15 parameters.

The first problem is that now I have to change my code specifically for ACML usage. The second problem is that there's no documentation for the additional parameters.

Where can I find documentation for the additional parameters? Is there a header file the comply with LAPACK/BLAS?
