pub unsafe extern "C" fn eyelink_position_prescaler() -> INT16

@ingroup messaging Returns the divisor used to convert integer eye data to floating point data.

@return Divisor (usually 10).

\b Example:

\code

#include 
UINT32 start_time;

eyecmd_printf("screen_write_prescale = 10");

start_time = current_msec();
while(current_msec() < start + 1000)
if (eyelink_command_result() == OK_RESULT)
{
eyemsg_printf("Position scalar %d",
eyelink_position_prescaler());
break;
}
\endcode
