Descrizione dettagliata

Common operations on file descriptors.

Except when documented otherwise, methods of this class are just thin wrappers around the libc functions with the same name, that check error results and throw exceptions if the functions failed.

Implementing what to do on construction and destruction is left to the subclassers: at the FileDescriptor level, the destructor does nothing and leaves the file descriptor open.

Definizione alla linea 144 del file sys.h.
