6 qb_log_callsites_register - If you are using dynamically loadable mod‐
7 ules via dlopen() and you load them after qb_log_init() then after you
8 load the module you will need to do the following to get the filters to
9 work in that module:
10
11
13 #include <qb/qblog.h>
14
15 int32_t qb_log_callsites_register(
16 struct qb_log_callsite *_start,
17 struct qb_log_callsite *_stop
18 );
19
21 _start = dlsym (dl_handle, QB_ATTR_SECTION_START_STR);
22 _stop = dlsym (dl_handle, QB_ATTR_SECTION_STOP_STR);
23 qb_log_callsites_register(_start, _stop);

27 An instance of this structure is created for each log message with the message-id.

30 struct qb_log_callsite {
31 const char *function;
32 const char *filename;
33 const char *format;
34 uint8_t priority;
35 uint32_t lineno;
36 uint32_t targets;
37 uint32_t tags;
38 const char *message_id;
