 * Every function should return an integer if possible. This integer should be
 * MOC_SUCCESS if the operation teminated successfully otherwise an error-code
 * telling the reason of the error is returned.
 *
 * For more information see Chapter 7.2 of the MPI 1.3 Standard.

/**

 *
 * Error-classes defined by the MPI-standard. Every error-code returned by a
 * MOC-function should belong to an error-class or be an error-class itself.
 * This enables implementation-independend error-handling.
 *
 * Value-range: 0 = MOC_SUCCESS < MOC_ERR_... <= MOC_ERR_LASTCODE
