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
4 
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.
7 
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.
10 
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
14 
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.
17 
18   PetscBLASInt is almost always 32 bit integers but can be 64 bit integers for certain usages of MKL and OpenBLAS BLAS/LAPACK libraries

44 -   routine - actual call to the routine including its arguments
45 
46    Level: developer

48    Developer Note:
49    This is so that when a user or external library routine results in a crash or corrupts memory, they get blamed instead of PETSc.
