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
PetscInt64value
Output Parameter#
b - the resulting
PetscIntvalue, orNULLif 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
