MPI_Pack_external function
Packs a datatype into contiguous memory, using the external32 format.
Syntax
int MPIAPI MPI_Pack_external(
_In_z_ char *datarep,
_In_ void *inbuf,
int incount,
MPI_Datatype datatype,
_Out_bytecap_(outsize) void *outbuf,
MPI_Aint outsize,
_Inout_ MPI_Aint *position
);
Parameters
datarep
Data representation.inbuf [in]
Start address of the input buffer.incount
Number of input data items.datatype
Datatype of each input data item.outbuf
Start address of the output buffer.outsize
Output buffer size, in bytes.position
Current position in buffer, 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.
