MPI_Sendrecv function
Sends and receives a message.
Syntax
int MPIAPI MPI_Sendrecv(
_In_ void *sendbuf,
int sendcount,
MPI_Datatype sendtype,
int dest,
int sendtag,
_Out_ void *recvbuf,
int recvcount,
MPI_Datatype recvtype,
int source,
int recvtag,
MPI_Comm comm,
_Out_ MPI_Status *status
);
Parameters
sendbuf [in]
Initial address of send buffer.sendcount
Number of elements in send buffer.sendtype
Type of elements in send buffer.dest
Rank of destination.sendtag
Send tag.recvbuf [out]
Initial address of receive buffer.recvcount
Number of elements in receive buffer.recvtype
Type of elements in receive buffer.source
Rank of source.recvtag
Receive tag.comm
Communicator.status [out]
Status object that refers to the receive operation.
Return value
Returns MPI_SUCCESS on success. Otherwise, the return value is an error code.
In Fortran, the return value is stored in the IERROR parameter.
