Member Function Documentation

set_log_handler()

static void rerun::Error::set_log_handler ( StatusLogHandler  handler, void *  userdata = nullptr  )

static

Sets global log handler called for handle.

The default will log to stderr, unless RERUN_STRICT is set to something truthy.

Parameters

handler	The handler to call, or nullptr to reset to the default.
userdata	Userdata pointer that will be passed to each invocation of the handler.

log, log_on_failure

handle()

void rerun::Error::handle

(

)

const

Handle this error based on the set log handler.

If there is no error, nothing happens.

If you have set a log handler with set_log_handler, it will be called. Else if the RERUN_STRICT env-var is set to something truthy, an exception will be thrown (if __cpp_exceptions are enabled), or the program will abort.

If no log handler is installed, and we are not in strict mode, the error will be logged to stderr.
