MPI_Aint_add - Returns the sum of base and disp

Input Parameters:

+ base - base address (integer)

- disp - displacement (integer)

Return value:

Sum of the base and disp argument

Notes:

MPI_Aint_Add produces a new MPI_Aint value that is equivalent to the sum of the

base and disp arguments, where base represents a base address returned by a call

to MPI_GET_ADDRESS and disp represents a signed integer displacement. The resulting

address is valid only at the process that generated base, and it must correspond

to a location in the same object referenced by base. The addition is performed in

a manner that results in the correct MPI_Aint representation of the output address,

as if the process that originally produced base had called\:
