pub unsafe extern "C" fn dc1394_iso_allocate_bandwidth(
    camera: *mut dc1394camera_t, 
    bandwidth_units: c_int
) -> Type

dc1394_iso_allocate_bandwidth: @param camera A camera handle. @param bandwidth_units The number of isochronous bandwidth units to allocate.

Allocates isochronous bandwidth. This functions allocates bandwidth in addition to any previous allocations. It may be called multiple times. The bandwidth is automatically re-allocated if there is a bus reset. The bandwidth is automatically released if this camera is freed or the application shuts down prematurely. If the bandwidth needs to persist beyond the lifetime of this application, call \a dc1394_iso_set_persist() first.

@return \a DC1394_SUCCESS if the operation succeeded. \a DC1394_FUNCTION_NOT_SUPPORTED if the current driver/platform does not allow bandwidth allocation. \a DC1394_NO_BANDWIDTH if there is not enough available bandwidth to support the allocation. In this case, no bandwidth is allocated.
