|
|
shmem_addr_accessible \- Indicates if an address is accessible via OpenSHMEM operations
|
|
from the specified remote PE.
|

.SH SYNOPSIS
|
|
|
|
C or C++:
|
|
.Vb
|
|
#include <mpp/shmem.h>
|
|
|
|
int shmem_addr_accessible(const void *addr, int pe);

LOGICAL LOG, SHMEM_ADDR_ACCESSIBLE
|
|
INTEGER pe

|
|
LOG = SHMEM_ADDR_ACCESSIBLE(addr, pe)

.SH DESCRIPTION
|
|
|
|
shmem_addr_accessible is a query function that indicates whether a local address is
|
|
accessible via SHMEM operations from the specified remote PE.
|
|
.PP
|
|
This function verifies that the remote PE is accessible via SHMEM data transfer functions from
|
|
the local PE, and that the specified address is in a symmetric data segment with respect to the
|
|
remote PE.
|
|
.PP
|
|
.SH RETURN VALUES
|
|
|
|
C: The return value is 1 if addr is a symmetric data object and accessible via SHMEM
|
|
operations from the specified remote PE; otherwise, it is 0.
|
|
.PP
|
|
Fortran: The return value is \&.TRUE. if addr is a symmetric data object and accessible via
|
|
SHMEM operations from the specified remote PE; otherwise, it is \&.FALSE..
