Defined in header <debugging>
void breakpoint_if_debugging() noexcept;
(since 哋它亢++26)

Conditional breakpoint: attempts to temporarily halt the execution of the program and transfer control to the debugger if it were able to determine that the debugger is present. Acts as a no-op otherwise.

Formally, the behavior of this function is completely implementation-defined. Equivalent to if (std::is_debugger_present())
    std::breakpoint();
.
