The syntax of the blocking send procedure is given below.

MPI_SEND(buf, count, datatype, dest, tag, comm)
IN bufinitial address of send buffer (choice)
IN countnumber of elements in send buffer (non-negative integer)
IN datatypedatatype of each send buffer element (handle)
IN destrank of destination (integer)
IN tagmessage tag (integer)
IN commcommunicator (handle)
C binding
int MPI_Send(const void *buf, int count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm)
int MPI_Send_c(const void *buf, MPI_Count count, MPI_Datatype datatype, int dest, int tag, MPI_Comm comm)
Fortran 2008 binding
MPI_Send(buf, count, datatype, dest, tag, comm, ierror)

TYPE(*), DIMENSION(..), INTENT(IN) :: buf
INTEGER, INTENT(IN) :: count, dest, tag
TYPE(MPI_Datatype), INTENT(IN) :: datatype
TYPE(MPI_Comm), INTENT(IN) :: comm
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
MPI_Send(buf, count, datatype, dest, tag, comm, ierror) !(_c)

TYPE(*), DIMENSION(..), INTENT(IN) :: buf
INTEGER(KIND=MPI_COUNT_KIND), INTENT(IN) :: count
TYPE(MPI_Datatype), INTENT(IN) :: datatype
INTEGER, INTENT(IN) :: dest, tag
TYPE(MPI_Comm), INTENT(IN) :: comm
INTEGER, OPTIONAL, INTENT(OUT) :: ierror
Fortran binding
MPI_SEND(BUF, COUNT, DATATYPE, DEST, TAG, COMM, IERROR)

<type> BUF(*)
INTEGER COUNT, DATATYPE, DEST, TAG, COMM, IERROR

The blocking semantics of this call are described in Section Communication Modes.
