我的带有MQ的C接收消息返回码2037
我运行C程序，它连接到MQ并尝试从中获取消息。 我总是收到一条消息：
MQGET以原因代码2037结束
这意味着MQ未打开，但MQOPEN CC = 0 RC = 0
MQ错误日志为空。
这是该计划

MQRC 2037是MQRC_NOT_OPEN_FOR_INPUT，您可以通过运行随IBM MQ Client或服务器安装提供的mqrc命令来查找此信息，下面是Linux服务器上的示例输出：
$ mqrc 2037 2037 0x000007f5 MQRC_NOT_OPEN_FOR_INPUT
您没有显示MQOPEN调用，但是如果它正在使用O_options ，则可以解释这一点，您目前有以下内容：
O_options = MQOO_OUTPUT + MQOO_FAIL_IF_QUIESCING;
这应该像下面这样：
O_options = MQOO_INPUT_AS_Q_DEF + MQOO_FAIL_IF_QUIESCING;
我建议您查看随IBM MQ安装提供的示例应用程序。 在Linux上，这些将位于/opt/mqm/samp 。 样本amqsget0.c与您的程序类似，只是它使用MQCONN而不是MQCONNX。
