NAME

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

SYNOPSIS

C or C++:

#include <mpp/shmem.h>
int shmem_addr_accessible(const void *addr, int pe);

Fortran:

INCLUDE "mpp/shmem.fh"
LOGICAL LOG, SHMEM_ADDR_ACCESSIBLE
INTEGER pe
LOG = SHMEM_ADDR_ACCESSIBLE(addr, pe)

DESCRIPTION

shmem_addr_accessible is a query function that indicates whether a local address is accessible via SHMEM operations from the specified remote PE.

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.

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.

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..
