Choice


Up: Data Types Next: Addresses Previous: Named constants

MPI functions sometimes use arguments with a choice (or union) data type. Distinct calls to the same routine may pass by reference actual arguments of different types. The mechanism for providing such arguments will differ from language to language. For Fortran, the document uses <type> to represent a choice variable, for C, we use (void *).
