MPI_Aint_diff(3)                      MPI                     MPI_Aint_diff(3)

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.
