The variables specified in the condition must be in scope at whatever line you set the breakpoint on, otherwise the expression wouldn't make sense!
条件中指定的变量必须在设置了断点的行中，否则表达式就没有什么意义！
We had to continue program execution twice to get to this point, however by setting a condition on the breakpoint we can make gdb halt only when "value" actually equals "div".
我们必须继续执行两次程序才会发生这种情况，但是只要在断点上设置一个条件就可以使gdb只在 "value" 与 "div"真正相等时暂停。
If a breakpoint such as number 1 was already defined at line 21 we could use the 'condition' command instead to set the condition on the breakpoint.
如果已经在第21行中设置了断点，如1号断点，则可以使用'condition '命令来代替在断点上设置条件。
Breakpoints can be set to unconditional using the 'condition' command specifying a breakpoint number without an expression, for example 'condition 1' sets breakpoint 1 to unconditional.
使用'condition '命令时，如果指定断点编号但又不指定表达式，可以将断点设置成无条件断点，例如，' condition1 '就将1号断点设置成无条件断点。
A breakpoint halts the debugger once it reaches a specific location or once a condition is met.
当达到某个特定位置或满足某个条件时，断点将暂停调试器。
