The return value is zero for a successful parse, and non-zero otherwise.
返回值为零，说明是一次成功的解析，否则返回的是非零值。
If the function succeeds, the return value is non-zero.
如果函数成功，则返回值非零。
Notice that when you run the command, the if statement for the last exit status is never reached because the script exits upon a non-zero return status of the cp command.
注意，当您运行该命令时，实现最终的退出状态的if语句将永远无法满足条件，因为脚本在遇到cp命令的非零返回状态时将退出。
Test programs generally use the standard Unix conventions: they return 0 in the event of a successful run and some non-zero value in the event of failure.
测试程序遵循标准的Unix习惯：如果测试通过则返回值为0，如果失败则返回一个非0 值。
And you should never unlock a mutex that you don't hold a lock for (otherwise, the pthread_mutex_unlock call will fail with a non-zero EPERM return value).
并且绝对不要对您未保持锁的互斥对象进行解锁操作(否则，pthread _ mutex_unlock调用将失败并带一个非零的eperm返回值)。
What does write (2) return of zero mean and will I eventually make progress (non-zero result)?
怎么写(2)零均值回归，最终我取得进步(非零结果)？
