"While it can be abused, the traditional C \"goto\" statement at least has "
"the benefit that lexical cues (the goto statement and the target label)  "
"allow the programmer to easily perceive the flow of control.  Nonlocal gotos "
"provide no such cues: multiple B<setjmp>()  calls might employ the same "
"I<jmp_buf> variable so that the content of the variable may change over the "
"lifetime of the application.  Consequently, the programmer may be forced to "
"perform detailed reading of the code to determine the dynamic target of a "
"particular B<longjmp>()  call.  (To make the programmer's life easier, each "
"B<setjmp>()  call should employ a unique I<jmp_buf> variable.)"
msgstr ""
"Хотя этим и можно злоупотребить, обычный оператор C «goto» имеет "
"преимущество в виде лексических отметок (оператор goto и метка перехода), "
"которые позволяют программисту легко понять поток выполнения. Нелокальные "
"переходы не имеют таких отметок: многократные вызовы B<setjmp>() могут "
"использовать одну переменную I<jmp_buf>, то есть контекст переменной может "
"изменяться на протяжении времени работы приложения. Следовательно, "
"программисту придёт вчитываться в код для определения динамической точки "
"перехода определённого вызова B<longjmp>() (для облегчения жизни "
"программиста в каждом вызове B<setjmp>() должна использоваться уникальная "
"переменная I<jmp_buf>)."
