PetscBLASIntCast#

casts a PetscInt (which may be 64 bits in size) to a PetscBLASInt (which may be 32 bits in size), generates an error if the PetscBLASInt is not large enough to hold the number.

Synopsis#

Not Collective

Input Parameter#

Output Parameter#

Notes#

Not available from Fortran

Errors if the integer is negative since PETSc calls to BLAS/LAPACK never need to cast negative integer inputs
