Function moduleGetReplyClient

app/redis-6.2.6/src/module.c:1479–1492

Return the client object the `RM_Reply*` functions should target. * Normally this is just `ctx->client`, that is the client that called * the module command, however in the case of thread safe contexts there * is no directly associated client (since it would not be safe to access * the client from a thread), so instead the blocked client object referenced * in the thread safe context, has a f

 * client object. Other contexts without associated clients are the ones
 * initialized to run the timers callbacks. */
