C++ (Cpp) plugin_construct Examples

Example #1

File: cfg-lexer.c Project: jszigetvari/syslog-ng

static CfgBlockGenerator *
cfg_lexer_find_generator(CfgLexer *self, GlobalConfig *cfg, gint context, const gchar *name)
{
  Plugin *p;
  CfgBlockGenerator *gen;

  p = plugin_find(&cfg->plugin_context, context | LL_CONTEXT_FLAG_GENERATOR, name);
  if (!p || !_is_generator_plugin(p))
    return NULL;

  gen = plugin_construct(p);
  return gen;
}

Example #2

File: msg-format.c Project: balabit/syslog-ng-3.3

/*
 * NOTE: options_init and options_destroy are a bit weird, because their
 * invocation is not completely symmetric:
 *
 *   - init is called from driver init (e.g. affile_sd_init),
 *   - destroy is called from driver free method (e.g. affile_sd_free, NOT affile_sd_deinit)
 *
 * The reason:
 *   - when initializing the reloaded configuration fails for some reason,
 *     we have to fall back to the old configuration, thus we cannot dump
 *     the information stored in the Options structure.
 *
 * For the reasons above, init and destroy behave the following way:
 *
 *   - init is idempotent, it can be called multiple times without leaking
 *     memory, and without loss of information
 *   - destroy is only called once, when the options are indeed to be destroyed
 *
 * As init allocates memory, it has to take care about freeing memory
 * allocated by the previous init call (or it has to reuse those).
 *
