There's a call to change the behaviour.
/*
* Sets the fork() action of the calling Fusionee within the world.
*/
void fusion_world_set_fork_action( FusionWorld *world,
FusionForkAction action );
typedef enum {
FFA_CLOSE,
FFA_FORK
} FusionForkAction;
You need to get the world from the DirectFB core:
fusion_world_set_fork_action( dfb_core_world(NULL), FFA_FORK );
Please include <src/core.h> and <fusion/fusion.h> for this.
I hope it helps, anyhow there should be an option for DirectFB to make it do
that itself.
