This can be cumbersome to maintain, and it can be more difficult to perform appropriate error checking (see the section, "Trap for errors") and to avoid unnecessary lookups.
这些代码维护起来会很麻烦，而为避免不必要的查找以及执行适当的错误检查就更加困难(参见“捕获错误”部分)。
The following system error codes are associated with these sensors and can be used to trigger alerts from the SNMP Trap Event Subscription configuration.
以下的系统错误代码与这些传感器相关，可用来触发SNMPTrapEventSubscription配置中的警报。
Otherwise, a trap occurs for find, and the exception handler emits the standard file not found error.
否则，发生中断以find（查找），并且异常处理程序发出标准的file not found（文件未找到）错误。
So you must be able to trap exceptions and do something intelligent: usually, that means to do nothing and let the overall process continue, silently ignoring the error.
所以必须能够捕获异常并进行适当的处理：通常，这意味着什么也不做并让整个过程继续，悄悄地忽略错误。
For example, imagine that you want to trap an error when trying to create a directory.
例如，假定您希望在尝试创建目录时跟踪错误。
The ERR goes with the signal list within the trap command. In the following example, a non-existent file is copied, which invokes an error
ERR在trap命令中提供了一个信号列表。
When you have learned to snatch the error code from the trap frame, it will be time for you to leave.
当你学习到如何从程序设计的陷阱中找出错误的程序码时，就是你离开的时候了。
Thus spake the master programmer: 'When you have learned to snatch the error code from the trap frame, it will be time for you to leave.
编程大师说道： “当你学会抓取框架中的错误代码时，你就可以出师了。”
