plucky (3) shmem_longlong_finc.openmpi.3.gz

SYNOPSIS

       C or C++:

          #include <mpp/shmem.h>

          int shmem_int_finc(int *target, int pe)

          long shmem_long_finc(long *target, int pe)

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

       Fortran:

          INCLUDE "mpp/shmem.fh"

          INTEGER pe
          INTEGER(KIND=4) SHMEM_INT4_FINC, target4
          INTEGER(KIND=8) SHMEM_INT8_FINC, target8

          ires4 = SHMEM_INT4_FINC(target4, pe)

          ires8 = SHMEM_INT8_FINC(target8, pe)

DESCRIPTION

       The fetch and increment routines retrieve the value at address target on PE pe, and  update  target  with
       the  result  of  incrementing  the  retrieved  value  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

       The contents that had been at the target address on the remote PE prior to the increment.
