Logging ======= Functions for logging and getting log data. .. code:: cpp #include <util/base.h> Logging Levels -------------- **LOG_ERROR** = 100 Use if there's a problem that can potentially affect the program, but isn't enough to require termination of the program. Use in creation functions and core subsystem functions. Places that should definitely not fail. **LOG_WARNING** = 200 Use if a problem occurs that doesn't affect the program and is recoverable. Use in places where failure isn't entirely unexpected, and can be handled safely. **LOG_INFO** = 300 Informative message to be displayed in the log. **LOG_DEBUG** = 400 Debug message to be used mostly by and for developers. Logging Functions ----------------- .. type:: void (*log_handler_t)(int lvl, const char *msg, va_list args, void *p) Logging callback. --------------------- .. function:: void base_set_log_handler(log_handler_t handler, void *param) void base_get_log_handler(log_handler_t *handler, void **param) Sets/gets the current log handler. --------------------- .. function:: void base_set_crash_handler(void (*handler)(const char *, va_list, void *), void *param) Sets the current crash handler. This may only be set once. --------------------- .. function:: void blogva(int log_level, const char *format, va_list args) Logging function (using a va_list). --------------------- .. function:: void blog(int log_level, const char *format, ...) Logging function. --------------------- .. function:: void bcrash(const char *format, ...) Crash function.
