Syntax
int MPIAPI MPI_Sendrecv_replace(
_Inout_ void *buf,
int count,
MPI_Datatype datatype,
int dest,
int sendtag,
int source,
int recvtag,
MPI_Comm comm,
_Out_ MPI_Status *status
);
Parameters
buf
Initial address of send and receive buffer.count
Number of elements in send and receive buffer.datatype
Type of elements in send and receive buffer.dest
Rank of destination.sendtag
Send message tag.source
Rank of source.recvtag
Receive message tag.comm
Communicator.status [out]
Status object.
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.
