Redis modules and blocking commands

[v5v6]

In the link https://redis.io/docs/reference/modules/modules-blocking-ops/
I found the latest example code is not correct, as RedisModule_IsBlockedReplyRequest should be used the general_func other than in the Example_RedisCommand function.
BRs,

int general_func(RedisModuleCtx *ctx, RedisModuleString **argv,
int argc)
{
if (RedisModule_IsBlockedReplyRequest(ctx)) {
long *mynumber = RedisModule_GetBlockedClientPrivateData(ctx);
return RedisModule_ReplyWithLongLong(ctx,mynumber);
} else if (RedisModule_IsBlockedTimeoutRequest(ctx)) {
return RedisModule_ReplyWithNull(ctx);
}
}

int Example_RedisCommand(RedisModuleCtx *ctx, RedisModuleString **argv,
int argc)
{

RedisModuleBlockedClient *bc =
    RedisModule_BlockClient(ctx,general_func,general_func,NULL,0);

pthread_t tid;
if (pthread_create(&tid,NULL,threadmain,bc) != 0) {
    RedisModule_AbortBlock(bc);
    RedisModule_ReplyWithError(ctx,"Sorry can't create a thread");
}

return REDISMODULE_OK;

}
