PetscIntCast

casts a MPI_Count, PetscInt64, PetscCount, or size_t to a PetscInt (which may be 32-bits in size), generates an error if the PetscInt is not large enough to hold the number.

Synopsis

static inline PetscErrorCode PetscIntCast(MPIU_Count a, PetscInt *b)

Not Collective; No Fortran Support

Input Parameter

• a - the PetscInt64 value

Output Parameter

• b - the resulting PetscInt value, or NULL if the result is not needed

Note

If integers needed for the applications are too large to fit in 32-bit ints you can ./configure using --with-64-bit-indices to make PetscInt use 64-bit integers
