QB_LOG_REAL_VA_(3)

💖 qb_log_real_va_ 💖

okay bestie, welcome to the libqb programmer's manual, and today's main character is qb_log_real_va_ — no cap, she's the one who actually pushes your log message out into the world. sit down, hydrate, let's get into it 🫶

✨ SYNOPSIS ✨

#include <qb/qblog.h>

void qb_log_real_va_(
    struct qb_log_callsite   *cs,
    va_list                   ap
);

---

🌸 DESCRIPTION 🌸

so like… there's literally nothing written here in the original. not a single line. she's giving mystery, she's giving silence, she's giving "the vibes speak for themselves" 💅 the function signature up in SYNOPSIS is doing all the talking, and the structs section right below is the lore drop. that's it, that's the description. iconic behaviour honestly.

---

🎀 STRUCTURES 🎀

okay so the tea here is: an instance of this structure gets created for each log message with the message-id. yes, every single one. she's thorough like that ✨

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;
};

that's the whole fit. function, filename, format, priority, lineno, targets, tags, message_id — every field exactly where she belongs, no notes 💜
