For example for debugging gui apps. Let's say we have function `on_event(event_type)` and you want to examine execution if `event_type == mouse_up`. In reality conditional breakpoint is the same as simple, but simple require support from code: ``` void on_event(event_type type) { if (type == mouse_up) { // set breakpoint here } } ``` Also useful to break depending on call stack[0] [0] https://sourceware.org/gdb/current/onlinedocs/gdb.html/Convenience-Funs.html#index-_0024_005fcaller_005fis_002c-convenience-function https://sourceware.org/gdb/current/onlinedocs/gdb.html/Conve...
