PetscIntCast
casts a PetscInt64 (which is 64 bits in size) 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
PETSC_STATIC_INLINE PetscErrorCode PetscIntCast(PetscInt64 a,PetscInt *b)
Not Collective
Input Parameter
a -the PetscInt64 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
