VisItSetBroadcastIntFunction

This function installs a callback function that allows libsim to broadcast an integer from the root process to slave processes.

Prototype void VisItSetBroadcastIntFunction(int (*)(int *, int));

Arguments A pointer to a callback function with prototype: int func(int *, int);

Returns None

Note All processors must call this function and install a callback function after initializing MPI. The callback function must be installed prior to VisItDetectInput.

Sample callback function:

static int visit_broadcast_int_callback(int *value, int sender) {

return MPI_Bcast(value, 1, MPI_INT, sender, MPI_COMM_WORLD);

}
