qb_log_callsites_register - If you are using dynamically loadable modules via
dlopen() and you load them after qb_log_init() then after you load the
module you will need to do the following to get the filters to work in that
module:
#include <qb/qblog.h>
int32_t qb_log_callsites_register(
struct qb_log_callsite *_start,
struct qb_log_callsite *_stop
);
_start = dlsym (dl_handle, QB_ATTR_SECTION_START_STR);
_stop = dlsym (dl_handle, QB_ATTR_SECTION_STOP_STR);
qb_log_callsites_register(_start, _stop);
An instance of this structure is created for each log message with the message-id.
struct qb_log_callsite {
const char *function;
const char *filename;
const char *format;
uint8_t priority;
uint32_t lineno;
uint32_t targets;
uint32_t tags;
const char *message_id;
};
