std::runtime_error(3) Library Functions Manual std::runtime_error(3) NAME std::runtime_error - One of two subclasses of exception. SYNOPSIS #include Inherits std::exception. Inherited by std::chrono::ambiguous_local_time, std::chrono::nonexistent_local_time, std::overflow_error, std::range_error, std::regex_error, std::system_error, and std::underflow_error. Public Member Functions runtime_error (const char *) runtime_error (const runtime_error &) noexcept runtime_error (const string &__arg) runtime_error (runtime_error &&) noexcept runtime_error & operator= (const runtime_error &) noexcept runtime_error & operator= (runtime_error &&) noexcept virtual const char * what () const noexcept Detailed Description One of two subclasses of exception. Runtime errors represent problems outside the scope of a program; they cannot be easily predicted and can generally only be caught as the program executes. Constructor & Destructor Documentation std::runtime_error::runtime_error (const string & __arg) [explicit] Takes a character string describing the error. Member Function Documentation virtual const char * std::runtime_error::what () const [virtual], [noexcept] Returns a C-style character string describing the general cause of the current error (the same string passed to the ctor). Reimplemented from std::exception. Reimplemented in std::experimental::filesystem::v1::filesystem_error, and std::filesystem::filesystem_error.
