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.
