This header is part of the diagnostics library.

Functions
breakpoint (C++26)	pauses the running program when called (function)
breakpoint_if_debugging (C++26)	calls std::breakpoint if std::is_debugger_present returns true (function)
is_debugger_present (C++26)	checks whether a program is running under the control of a debugger (function)

Synopsis

// all freestandingnamespace std {// debugging utilityvoid breakpoint()noexcept;void breakpoint_if_debugging()noexcept;bool is_debugger_present()noexcept;}
