PetscBLASIntCast#
casts a MPI_Count, PetscInt, PetscCount or PetscInt64 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(MPIU_Count a, PetscBLASInt *b)
Not Collective; No Fortran Support
Input Parameter#
a - the
PetscIntvalue
Output Parameter#
b - the resulting
PetscBLASIntvalue, orNULLif the result is not needed
Note#
Errors if the integer is negative since PETSc calls to BLAS/LAPACK never need to cast negative integer inputs
