[edit] Exceptions
The class exception provides a common interface to signal for error conditions through the throw expression.
[edit] Exception categories
Several convenience classes are predefined 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.
[edit] Error numbers
Several macros are available, that provide POSIX error number support. An errno variable is also supported, a separate value is given to each thread.(C++11 feature)
[edit] Assertions
Assertions help to implement checking of preconditions in programs.
Defined in header
<cassert> | ||
|
aborts the program if the user-specified condition is not true. May be disabled for release builds (function macro) |
static_assert declaration renders the program ill-formed if the user-specified condition is not true (C++11 feature).
