pub unsafe extern "C" fn dc1394_iso_release_bandwidth(
    camera: *mut dc1394camera_t, 
    bandwidth_units: c_int
) -> Type

dc1394_iso_release_bandwidth: @param camera A camera handle. @param bandwidth_units The number of isochronous bandwidth units to free.

Releases previously allocated isochronous bandwidth. Each \a dc1394camera_t keeps track of a running total of bandwidth that has been allocated. Released bandwidth is subtracted from this total for the sake of automatic re-allocation and automatic release on shutdown. It is also acceptable for a camera to release more bandwidth than it has allocated (to clean up for another process for example). In this case, the running total of bandwidth is not affected. It is acceptable to release more bandwidth than is allocated in total for the bus. In this case, all bandwidth is released and the function succeeds.

@return \a DC1394_SUCCESS if the operation succeeded. \a DC1394_FUNCTION_NOT_SUPPORTED if the current driver/platform does not allow bandwidth release.
