+mpi-type-mismatch
+=================
+
+This check verifies if buffer type and MPI (Message Passing Interface) datatype
+pairs match for used MPI functions. All MPI datatypes defined by the MPI
+standard (3.1) are verified by this check. User defined typedefs, custom MPI
+datatypes and null pointer constants are skipped, in the course of verification.
+
+Example:
+.. code:: c++
+ // In this case, the buffer type matches MPI datatype.
+ char buf;
+ MPI_Send(&buf, 1, MPI_CHAR, 0, 0, MPI_COMM_WORLD);
+
+ // In the following case, the buffer type does not match MPI datatype.
+ int buf;
+ MPI_Send(&buf, 1, MPI_CHAR, 0, 0, MPI_COMM_WORLD);
