Системное программирование в UNIX средствами Free Pascal

       

Когда работа над книгой подходила


Когда работа над книгой подходила к концу, была выпущена новая версия компилятора Free Pascal, в котором де-юре зафиксирована возможность использования интерфейса системных вызовов не только в ОС семейства Linux/BSD, но и других клонов UNIX. Для того, чтобы скомпилировать компилятором версии 2.0 программы, представленные в книге, следует заменить в них подключаемый модуль linux на oldlinux. Платформенно-независимая функциональность модуля linux разделена между unix, unixtype, baseunix и unixutil. В модуль X86 вынесены части, специфичные для X86-архитектуры.

Для удобства перехода на новую версию компилятора приводим таблицу соответствия модулей в разных версиях компилятора.
