NAME

       MPI_Aint_diff -  Returns the difference between addr1 and addr2

SYNOPSIS

       MPI_Aint MPI_Aint_diff(MPI_Aint addr1, MPI_Aint addr2)

INPUT PARAMETERS

       addr1  - minuend address (integer)
       addr2  - subtrahend address (integer)

RETURN VALUE

       Difference between addr1 and addr2

NOTES

       MPI_Aint_diff  produces a new MPI_Aint value that is equivalent to the difference between addr1 and addr2
       arguments, where addr1 and addr2 represent addresses returned by calls to MPI_GET_ADDRESS. The  resulting
       address  is valid only at the process that generated addr1 and addr2, and addr1 and addr2 must correspond
       to locations in the same object in the same process. The  difference  is  calculated  in  a  manner  that
       results  the  signed  difference  from  addr1  to  addr2,  as if the process that originally produced the
       addresses had called
       (char *) addr1 - (char *) addr2

       on the addresses initially passed to MPI_GET_ADDRESS.
