C 从linux代码到qnx代码有哪些变化？

我创建了一个套接字，通过ip地址和端口号从客户端接收数据。我创建了一个计时器，每2ms、10ms和100ms调用一次任务。上面的代码在linux上运行良好。但是如何将上述代码转换为QNX RTOS。我应该为QNX RTO做哪些更改。谁能帮帮我吗

如果我在qnx中使用相同的代码，那么它将在int fd_2ms=create_timer；时崩溃

请记住，QNX与Linux基本相同。如果我在Linux中通过更改库来使用上述代码，那么它将在create_定时器处崩溃；功能仅限！！！你能详细说明一下破裂的原因吗？你有编译器错误吗？链接器错误？运行时错误？请编辑您的问题，以包含这些信息，以及可能出现的编译器错误（如果有）的完整且未经编辑的日志。首先，您在Linux和QNX以及任何其他POSIX平台上使用的是错误的。timer_create只返回一个布尔成功/失败指示器，它是调用timer_settime时需要使用的timer_id。如果您的程序是为Linux工作的，那么您就很幸运了！可能您创建的第一个计时器的id为0，您只是更改了一个计时器，而不是三个不同的计时器。
