env类型jmp_buf到一个变量保存当前的执行上下文。这个变量可以在以后用来恢复当前的执行上下文longjmp功能。即，当呼叫longjmp功能，继续执行在特定呼叫站点构造jmp_buf变量传递到longjmp。在这种情况下，setjmp回报寿值传递给longjmpOriginal:
Saves the current execution context into a variable
env of type jmp_buf. This variable can later be used to restore the current execution context by longjmp function. That is, when a call to longjmp function is made, the execution continues at the particular call site that constructed the jmp_buf variable passed to longjmp. In that case setjmp returns tho value passed to longjmp.The text has been machine-translated via Google Translate.
