      1: /*
      2:   This file dispatches between various header files for blas/lapack distributions to handle the name mangling.
      3:   It also provides C prototypes for all the BLAS/LAPACK functions that PETSc uses

      5:   This is not included automatically by petscsys.h because some external packages include their own prototypes for
      6:   certain BLAS/LAPACK functions that conflict with the ones given here. Hence this should only be included when needed.

      8:   The BLAS/LAPACK name mangling is almost (but not always) the same as the Fortran mangling; and exists even if there is
      9:   not Fortran compiler.

     11:   PETSC_BLASLAPACK_UNDERSCORE BLAS/LAPACK function have an underscore at the end of each function name
     12:   PETSC_BLASLAPACK_CAPS BLAS/LAPACK function names are all in capital letters
     13:   PETSC_BLASLAPACK_C BLAS/LAPACK function names have no mangling

     15:   PETSC_BLASLAPACK_SINGLEISDOUBLE - for Cray systems where the BLAS/LAPACK single precision (i.e. Fortran single precision is actually 64 bits)
     16:                                     old Cray vector machines used to be this way, it is is not clear if any exist now.

     18:   PetscBLASInt is almost always 32 bit integers but can be 64 bit integers for certain usages of MKL and OpenBLAS BLAS/LAPACK libraries
