The examples in this section use intracommunicators.
Example
Broadcast 100 ints from process 0 to every process in the group.
MPI_Comm comm;
int array[100];
int root=0;
...
MPI_Bcast(array, 100, MPI_INT, root, comm);
As in many of our example code fragments, we assume that some
of the variables (such as comm in the above) have been assigned
appropriate values.
