MPI_Get_elements function - Message Passing Interface (original) (raw)
Returns the number of basic elements in a datatype.
Syntax
int MPIAPI MPI_Get_elements(
_In_ MPI_Status *status,
MPI_Datatype datatype,
_Out_ int *count
);
Parameters
- status [in]
Return status of receive operation. - datatype
Datatype used by receive operation. - count [out]
Number of received basic elements.
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.
Fortran
MPI_GET_ELEMENTS(STATUS, DATATYPE, COUNT, IERROR)
INTEGER STATUS(MPI_STATUS_SIZE), DATATYPE, COUNT, IERROR
Remarks
If the size of the datatype is zero and the amount of data returned as determined by status is also zero, this routine will return a count of zero.
