✨ QB_LOG_CA...S_REGISTER(3) ✨

okay bestie, welcome to the libqb Programmer's Manual 💖 this one's called qb_log_callsites_register and it's giving "my plugin has trust issues" energy. let's get into it 🌸

💅 NAME 💅

qb_log_callsites_register — okay so picture this: you're 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. that's literally it, that's the whole job. she's a fixer 🔥

🎀 SYNOPSIS 🎀

#include <qb/qblog.h>

int32_t qb_log_callsites_register(
    struct qb_log_callsite   *_start,
    struct qb_log_callsite   *_stop
);

🦋 DESCRIPTION 🦋

so like, here's the vibe, fr fr:

_start = dlsym (dl_handle, QB_ATTR_SECTION_START_STR);
_stop = dlsym (dl_handle, QB_ATTR_SECTION_STOP_STR);
qb_log_callsites_register(_start, _stop);

that's the move. grab your _start and _stop out of the dl_handle with dlsym, then hand them over to qb_log_callsites_register. filters? working. slay ✨

👑 STRUCTURES 👑

an instance of this structure is created for each log message with the message-id. iconic behaviour honestly 🫶

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;
};
