Direct, low-level interface to the system MPI library.
This low-level interface provides direct access to the unmanaged
MPI library provided by the system. It is by nature unsafe, and
should only be used by programmers experienced both in the use
of MPI from lower-level languages (e.g., C, Fortran) and with an
understanding of the interaction between managed and unmanaged
code, especially those issues that pertain to memory
pinning/unpinning.
The Unsafe..::.MPI_Status type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | Equals | Indicates whether this instance and a specified object are equal. (Inherited from ValueType.) |
 | Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetHashCode | Returns the hash code for this instance. (Inherited from ValueType.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns the fully qualified type name of this instance. (Inherited from ValueType.) |
Fields
| Name | Description | |
|---|---|---|
 | cancelled |
This field is only available if the underlying MPI is MS-MPI.
|
| count |
This field is only available if the underlying MPI is MS-MPI.
|
| MPI_ERROR |

TODO: We need a higher-level facility for dealing with this.
|
| MPI_SOURCE |
