Detailed Description

Receiving operations return a status-object holding information about the message.

There are three Fields of the status-Struct which are predefined by the MPI-Standard: MOC_SOURCE gives the message-source, MOC_TAG gives the message-tag and MOC_ERROR gives an error-code (not implemented by MOC at the moment). To get the number of element the function MOC_Get_count should be used.
