PetscCountCast

casts a PetscCount 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 PetscCountCast(PetscCount a,PetscInt *b)
Not Collective

Input Parameter

a - the PetscCount value

Output Parameter

b - the resulting PetscInt value

Notes

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 ints

Not available from Fortran
