Serviços Genéricos do Sistema Operacional

Os módulos descritos neste capítulo fornecem interfaces aos recursos do sistema operacional e que estão disponíveis em (quase) todos os sistemas operacionais, como arquivos e um relógio. As interfaces geralmente são modeladas após as interfaces Unix ou C, mas elas também estão disponíveis na maioria dos outros sistemas. Aqui temos uma visão geral:
