MPI_TESTANY(3)MPI_TESTANY(3)NAMEMPI_Testany - Tests for completion of any previously initiated
communication
SYNOPSIS
C:
#include <mpi.h>
int MPI_Testany( count, array_of_requests, index,
flag, status )
int count;
MPI_Request array_of_requests[];
int *index, *flag;
MPI_Status *status;
C++:
#include <mpi.h>
static bool Request::Testany(
int count,
Request array_of_requests[],
int& index)
Fortran:
INCLUDE "mpif.h" (or USE MPI)
LOGICAL flag
INTEGER count, array_of_requests(*), index,
status(MPI_STATUS_SIZE), ierror
CALL MPI_TESTANY(count, array_of_requests(*), index, flag,
status(MPI_STATUS_SIZE), ierror)
STANDARDS
This release implements the MPI 1.2 standard, as documented by the MPI
Forum in the spring 1997 release of MPI: A Message Passing Interface
Standard.

MPI_TESTANY(3)MPI_TESTANY(3)
array_of_requests
Specifies the array of requests (array of handles)
index Returns the index of the operation that completed, or the value
of MPI_UNDEFINED if no operation completed (integer)
flag Returns a value of true if one of the operations is complete
(logical)
status Returns the status object (status)
ierror Specifies the return code value for successful completion,
which is in MPI_SUCCESS. MPI_SUCCESS is defined in the mpif.h
file.
