MPI_SENDRECV(3)MPI_SENDRECV(3)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_Sendrecv routine sends and receives a message. This routine
accepts the following parameters:
sendbuf Specifies the initial address of the send buffer (choice)
sendcount Specifies the number of elements in the send buffer
(integer)
sendtype Specifies the type of elements in the send buffer (handle)
dest Specifies the rank of the destination (integer)
sendtag Specifies the send tag (integer)
recvcount Specifies the number of elements in the receive buffer
(integer)
recvtype Specifies the type of elements in the receive buffer
(handle)
source Specifies the rank of the source (integer)
recvtag Specifies the receive tag (integer)
comm Specifies the communicator (handle)
recvbuf Returns the initial address of the receive buffer (choice)
status Returns the status object (as it relates to the receive
operation) (status)
ierror Specifies the return code value for successful completion,
which is in MPI_SUCCESS. MPI_SUCCESS is defined in the
mpif.h file.
