8.1.1.1. Modifying Mode Settings Within an App
The mode settings can be modified within an application by calling
MO_currentOptions
to get the current mode settings into the mode option array,
MO_option
. After modifying the mode setting options, a call to
MO_digestOptions
will cause the new mode settings to take affect by sending
out the appropriate mode notification messages.
A simple example of setting the split screen ratio to the 50/50 setting follows:
MO_currentOptions();
MO_option[MO_OPT_SPLIT_RATIO] = D_SPLIT_RATIO_1_1;
MO_digestOptions(H_NULL);
