Event queue overflowed. Number of event lost:

EVENT_OFLOW

Development error. There was not enough room in the event queue to post the message. Make the event queue larger by setting the global variable _evq_size before calling vv_init(). You will then need to recompile your main program and relink. The default value for _evq_size is set in vv_main.h. The following is an example of setting _evq_size:

#include <vv_str.h>
#include <vv_main.h>

int main(void)
{
_evq_size = 50;
vv_init();
.
.
vv_exit();
return(0);
}
