datatype used to represent 'int' parameters to MPI functions.
<P>
Notes: usually this is the same as <A HREF="../Sys/PetscInt.html#PetscInt">PetscInt</A>, but if PETSc was built with --with-64-bit-indices but
standard C/Fortran integers are 32 bit then this is NOT the same as <A HREF="../Sys/PetscInt.html#PetscInt">PetscInt</A> it remains 32 bit
<P>
PetscMPIIntCheck(a) checks if the given <A HREF="../Sys/PetscInt.html#PetscInt">PetscInt</A> a will fit in a <A HREF="../Sys/PetscMPIInt.html#PetscMPIInt">PetscMPIInt</A>, if not it generates a
PETSC_ERR_ARG_OUTOFRANGE.
