SYNOPSIS

       C or C++:

          #include <mpp/shmem.h>

          int shmem_int_inc(int *target, int pe)

          long shmem_long_inc(long *target, int pe)

          long long shmem_longlong_inc(long long *target, int pe)

       Fortran:

          INCLUDE "mpp/shmem.fh"

          INTEGER pe
          INTEGER(KIND=4) SHMEM_INT4_INC, target4
          INTEGER(KIND=8) SHMEM_INT8_INC, target8

          ires4 = SHMEM_INT4_INC(target4, pe)

          ires8 = SHMEM_INT8_INC(target8, pe)

DESCRIPTION

       The atomic increment routines replace the value  of  target  with  its  value  incremented  by  one.  The
       operation  must  be completed without the possibility of another process updating target between the time
       of the fetch and the update.

       The arguments are as follows:

       target The remotely accessible integer data object to be updated on the remote PE.  The  type  of  target
              should match that implied in the SYNOPSIS section.

       pe     An  integer  that  indicates  the  PE  number upon which target is to be updated. If you are using
              Fortran, it must be a default integer value.

NOTES

       The term remotely accessible is defined in intro_shmem(3).

RETURN VALUES

       None.
