SHMEM_FINC(3)SHMEM_FINC(3)NAME
shmem_int4_finc, shmem_int8_finc, shmem_int_finc, shmem_long_finc,
shmem_longlong_finc - Performs an atomic fetch-and-increment operation
on a remote data object
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:
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
These functions perform a fetch-and-increment operation. The target
on processing element (PE) pe is increased by one and the function
returns the previous contents of target as an atomic operation.
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 on 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.
