void dbug	(	const char *	keyword,

inline

A type-safe interface to DBUG_EXECUTE_IF, where the debug action to activate when the keyword is provided is given as a callable object (typically a lambda).

Note: The body of the callable will be checked by the compiler even in optimized mode.

Parameters

keyword	String literal which will enable this debug action.
clos	Callable object taking no arguments which will be called in debug mode if the keyword is enabled.

◆ my_abort()

void my_abort ( )

Calls our own implementation of abort, if specified, or std's abort().

◆ set_my_abort()

void set_my_abort ( void(*)() new_my_abort_func )

Sets a new function to be called on my_abort().

Parameters

new_my_abort_func pointer to a new my_abort function. It can't be [[noreturn]] as pointers to methods can't have attributes.
