Returns the upper bound on the amount of space needed to pack a message using MPI_Pack_external.
Syntax
int MPIAPI MPI_Pack_external_size(
_In_z_ char *datarep,
int incount,
MPI_Datatype datatype,
_Out_ MPI_Aint *size
);
Parameters
datarep
Data representation.incount
Number of input data items.datatype
Datatype of each input data item.size [out]
Output buffer size, in bytes.
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.
