libpkgconf `cache` module ========================= The libpkgconf `cache` module manages a package/module object cache, allowing it to avoid loading duplicate copies of a package/module. A cache is tied to a specific pkgconf client object, so package objects should not be shared across threads. .. c:function:: pkgconf_pkg_t *pkgconf_cache_lookup(const pkgconf_client_t *client, const char *id) Looks up a package in the cache given an `id` atom, such as ``gtk+-3.0`` and returns the already loaded version if present. :param pkgconf_client_t* client: The client object to access. :param char* id: The package atom to look up in the client object's cache. :return: A package object if present, else ``NULL``. :rtype: pkgconf_pkg_t * .. c:function:: void pkgconf_cache_add(pkgconf_client_t *client, pkgconf_pkg_t *pkg) Adds an entry for the package to the package cache. The cache entry must be removed if the package is freed. :param pkgconf_client_t* client: The client object to modify. :param pkgconf_pkg_t* pkg: The package object to add to the client object's cache. :return: nothing .. c:function:: void pkgconf_cache_remove(pkgconf_client_t *client, pkgconf_pkg_t *pkg) Deletes a package from the client object's package cache. :param pkgconf_client_t* client: The client object to modify. :param pkgconf_pkg_t* pkg: The package object to remove from the client object's cache. :return: nothing .. c:function:: void pkgconf_cache_free(pkgconf_client_t *client) Releases all resources related to a client object's package cache. This function should only be called to clear a client object's package cache, as it may release any package in the cache. :param pkgconf_client_t* client: The client object to modify.
