loc_set_log_callback - Set a callback for log messages

typedef void (*loc_log_callback)(struct loc_ctx* ctx, void* data, int priority, const char* file, int line, const char* fn, const char* format, va_list args);

void loc_set_log_callback(struct loc_ctx* ctx, loc_log_callback callback, void* data);

libloc can use the calling application’s logging system by setting this callback.

It will be called once for each log message according to the configured log priority (see loc_set_log_priority(3)).

data is an opaque pointer which is passed through to the callback on every invocation.

This function replaces the deprecated loc_set_log_fn(3).
