Struct `vpkc_update_options_t`

struct vpkc_update_options_t
{
    bool AllowVersionDowngrade;

    char* ExplicitChannel;

    int32_t MaximumDeltasBeforeFallback;
};

Options to customise the behaviour of UpdateManager.

Variable `vpkc_update_options_t::AllowVersionDowngrade`

bool AllowVersionDowngrade;

Allows UpdateManager to update to a version that’s lower than the current version (i.e. downgrading).

This could happen if a release has bugs and was retracted from the release feed, or if you’re using ExplicitChannel to switch channels to another channel where the latest version on that channel is lower than the current version.

Variable `vpkc_update_options_t::ExplicitChannel`

char* ExplicitChannel;

This option should usually be left None/NULL.

Overrides the default channel used to fetch updates. The default channel will be whatever channel was specified on the command line when building this release. For example, if the current release was packaged with ‘–channel beta’, then the default channel will be ‘beta’. This allows users to automatically receive updates from the same channel they installed from. This options allows you to explicitly switch channels, for example if the user wished to switch back to the ‘stable’ channel without having to reinstall the application.

Variable `vpkc_update_options_t::MaximumDeltasBeforeFallback`

int32_t MaximumDeltasBeforeFallback;

Sets the maximum number of deltas to consider before falling back to a full update.

The default is 10. Set to a negative number (eg. -1) to disable deltas.

    bool IsDowngrade;
};

Holds information about the current version and pending updates, such as how many there are, and access to release notes.

Member variables

DeltasToTargetCount — The number of elements in the DeltasToTarget array.

Variable `vpkc_update_info_t::IsDowngrade`

Create a new CUSTOM update source with user-provided callbacks to fetch release feeds and download assets.

You can report download progress using vpkc_source_report_progress. Note that the callbacks must be valid for the lifetime of any UpdateManager’s that use this source. You should call vpkc_free_source to free the source, but note that if the source is still in use by an UpdateManager, it will not be freed until the UpdateManager is freed. Therefore to avoid possible issues, it is recommended to create this type of source once for the lifetime of your application. @param cb_release_feed A callback to fetch the release feed. @param cb_free_release_feed A callback to free the memory allocated by cb_release_feed. @param cb_download_entry A callback to download an asset. @param p_user_data Optional user data to be passed to the callbacks. @returns A new vpkc_update_source_t instance, or null on error. If null, the error will be available via vpkc_get_last_error.

Function `vpkc_source_report_progress`

void vpkc_source_report_progress(size_t progress_callback_id, int16_t progress);

Sends a progress update to the callback with the specified ID. This is used by custom update sources created with vpkc_new_source_custom_callback to report download progress.

@param p_source A pointer to a custom UpdateSource. @param p_options Optional extra configuration for update manager. @param p_locator Optional explicit path configuration for Velopack. If null, the default locator will be used. @param p_manager A pointer to where the new vpkc_update_manager_t* instance will be stored. @returns True if the update manager was created successfully, false otherwise. If false, the error will be available via vpkc_get_last_error.

@param p_manager The update manager instance. @param p_update A pointer to where the new vpkc_update_info_t* instance will be stored if an update is available. @returns A vpkc_update_check_t value indicating the result of the check. If an update is available, the value will be HasUpdate and p_update will be populated.

Downloads the specified updates to the local app packages directory. Progress is reported back to the caller via an optional callback.

This function will acquire a global update lock so may fail if there is already another update operation in progress.

If the update contains delta packages and the delta feature is enabled this method will attempt to unpack and prepare them.
If there is no delta update available, or there is an error preparing delta packages, this method will fall back to downloading the full version of the update. @param p_manager The update manager instance. @param p_update The update info object from vpkc_check_for_updates. @param cb_progress An optional callback to report download progress (0-100). @param p_user_data Optional user data to be passed to the progress callback. @returns true on success, false on failure.

This will launch the Velopack updater and tell it to wait for this program to exit gracefully.

You should then clean up any state and exit your app. The updater will apply updates and then (if specified) restart your app. The updater will only wait for 60 seconds before giving up. @param p_manager The update manager instance. @param p_asset The asset to apply. This can be from vpkc_update_pending_restart or vpkc_update_info_get_target_asset. @param b_silent True to attempt to apply the update without showing any UI. @param b_restart True to restart the app after the update is applied. @param p_restart_args An array of command line arguments to pass to the new process when it’s restarted. @param c_restart_args The number of arguments in p_restart_args. @returns true on success, false on failure. If false, the error will be available via vpkc_get_last_error.

Function `vpkc_unsafe_apply_updates`

bool vpkc_unsafe_apply_updates(vpkc_update_manager_t* p_manager, vpkc_asset_t* p_asset, bool b_silent, uint32_t dw_wait_pid, bool b_restart, char** p_restart_args, size_t c_restart_args);

This will launch the Velopack updater and optionally wait for a program to exit gracefully.

This method is unsafe because it does not necessarily wait for any / the correct process to exit before applying updates. The vpkc_wait_exit_then_apply_updates method is recommended for most use cases. If dw_wait_pid is 0, the updater will not wait for any process to exit before applying updates (Not Recommended). @param p_manager The update manager instance. @param p_asset The asset to apply. This can be from vpkc_update_pending_restart or vpkc_update_info_get_target_asset. @param b_silent True to attempt to apply the update without showing any UI. @param dw_wait_pid The process ID to wait for before applying updates. If 0, the updater will not wait. @param b_restart True to restart the app after the update is applied. @param p_restart_args An array of command line arguments to pass to the new process when it’s restarted. @param c_restart_args The number of arguments in p_restart_args. @returns true on success, false on failure. If false, the error will be available via vpkc_get_last_error.

Function `vpkc_app_set_auto_apply_on_startup`

void vpkc_app_set_auto_apply_on_startup(bool b_auto_apply);

Set whether to automatically apply downloaded updates on startup. This is ON by default.
