#define MPICaptureNOT_MAPPED (-1)
Capture objects are associated with the controller and are not mapped to any hardware resources under default conditions. MPICaptureNOT_MAPPED is assigned to:
int32_t captureMotorNumber; int32_t feedbackMotorNumber;
when mpiCaptureConfigGet is called for the first time on a capture object. After a capture object has been used once, the resource mapping will remain in place until it is reassigned.
