Exception handling

The header <exception> provide several classes and functions related to exception handling in C++ programs.

Defined in header <exception>
Capture and storage of exception objects
Handling of failures in exception handling
Handling of exception specification violations

Exception categories

Several convenience classes are predefined in the header <stdexcept> to report particular error conditions. These classes can be divided into two categories: logic errors and runtime errors. Logic errors are a consequence of faulty logic within the program and may be preventable. Runtime errors are due to events beyond the scope of the program and can not be easily predicted.

Defined in header <stdexcept>
exception class to indicate violations of logical preconditions or class invariants
(class)
exception class to report invalid arguments
(class)
exception class to report domain errors
(class)
exception class to report attempts to exceed maximum allowed size
(class)
exception class to report arguments outside of expected range
(class)
exception class to indicate conditions only detectable at run time
(class)
exception class to report range errors in internal computations
(class)
exception class to report arithmetic overflows
(class)
exception class to report arithmetic underflows
(class)

Error numbers

Defined in header <cerrno>
macro which expands to POSIX-compatible thread-local error number variable
(macro constant)
macros for standard POSIX-compatible error conditions
(macro constant)

Assertions

Assertions help to implement checking of preconditions in programs.

Template:dcl list keyword
Defined in header <cassert>
aborts the program if the user-specified condition is not Template:cpp. May be disabled for release builds
(function macro)

System error

The header <system_error> defines types and functions used to report error conditions originating from the operating system, streams I/O, Template:cpp, or other low-level APIs.
