Function libdc1394_sys::dc1394_iso_set_persist

pub unsafe extern "C" fn dc1394_iso_set_persist(
    camera: *mut dc1394camera_t
) -> Type

dc1394_iso_set_persist @param camera A camera handle.

Calling this function will cause isochronous channel and bandwidth allocations to persist beyond the lifetime of this dc1394camera_t instance. Normally (when this function is not called), any allocations would be automatically released upon freeing this camera or a premature shutdown of the application (if possible). For this function to be used, it must be called prior to any allocations or an error will be returned.

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