int main(int argc, char *argv[]) { int me, count; void *data; ...

 MPI_Init(&argc, &argv); 
 MPI_Comm_rank(MPI_COMM_WORLD, &me); 

 if(me == 0) 
 { 
     /* get input, create buffer ``data'' */ 
     ... 
 } 

 MPI_Bcast(data, count, MPI_BYTE, 0, MPI_COMM_WORLD); 

 ... 
 MPI_Finalize(); 
 return 0; 

}

This example illustrates the use of a collective communication.
