The Linux Manuals (man pages) document is an important part of Linux documents. Linux Manuals are organized as several sections. Each section has a group of commands for a specific area in Linux usage, administration or development.
std::rewind – std::rewind Synopsis Defined in header<cstdio> void rewind(std::FILE *stream); Moves the file position indicator to the beginning of the given file stream. The function is equivalent to std::fseek(stream, 0, SEEK_SET);, except that end-of-file and error indicators are cleared. The function drops any effects from previous calls to ungetc. Parameters stream – file stream to…

std::rethrow_if_nested – std::rethrow_if_nested Synopsis Defined in header<exception> template <class E> (since C++ 11) void rethrow_if_nested(const E &e); If E is not a polymorphic class type, or if std::nested_exception is an inaccessible or ambiguous base class of E, there is no effect. Otherwise, performs if (auto p = dynamic_cast<const std::nested_exception *>(std::addressof(e))) p->rethrow_nested(); Parameters e – the…
std::rethrow_exception – std::rethrow_exception Synopsis Defined in header <exception> [[noreturn]] void rethrow_exception( std::exception_ptr p ) (since C++11) Throws the previously captured exception object, referred to by the exception pointer p.
