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#
static inline PetscErrorCode PetscBLASIntCast(PetscInt a, PetscBLASInt *b)
Not Collective
Input Parameter#
a - the
PetscIntvalue
Output Parameter#
b - the resulting
PetscBLASIntvalue
Notes#
Not available from Fortran
Errors if the integer is negative since PETSc calls to BLAS/LAPACK never need to cast negative integer inputs
