MPI_Recv_init - Builds a handle for a receive
SYNOPSIS
C:
#include <mpi.h>
int MPI_Recv_init( buf, count, datatype, source,
tag, comm, request )
void *buf;
int count;
MPI_Request *request;
MPI_Datatype datatype;
int source;
int tag;
MPI_Comm comm;
C++:
#include <mpi.h>
Prequest Comm::Recv_init(
void* buf,
int count,
const Datatype& datatype,
int source,
int tag) const
Fortran:
INCLUDE "mpif.h" (or USE MPI)
<type> BUF(*)
INTEGER count, datatype, source, tag, comm, request, ierror
CALL MPI_RECV_INIT(buf, count, datatype, source, tag, comm, request, 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.
DESCRIPTION
The MPI_Recv_init routine builds a handle for a receive
operation. This routine accepts the following parameters:
buf Specifies the initial address of the receive
buffer (choice)
count Specifies the number of elements received
datatype Specifies the type of each element (handle)
source Specifies the rank of source or MPI_ANY_SOURCE
(integer)
tag Specifies the message tag or MPI_ANY_TAG
(integer)
comm Specifies the communicator (handle)
request Returns the communication request (handle)
ierror Specifies the return code value for successful
completion, which is in MPI_SUCCESS.
MPI_SUCCESS is defined in the mpif.h file.
