QB_LOG_TARGET_FORMAT(3)

✨ QB_LOG_TARGET_FORMAT ✨

okay bestie, so this one lives in the libqb Programmer's Manual, and it's all about making your log lines look cute — well, look formatted, anyway 💅

---

🎀 NAME 🎀

qb_log_target_format — it formats the callsite and timestamp info according to the format. that's literally the whole job, no cap ✨

---

🦋 SYNOPSIS 🦋

#include <qb/qblog.h>

void qb_log_target_format(
    int32_t                   target,
    struct qb_log_callsite   *cs,
    struct timespec          *timestamp,
    const char               *formatted_message,
    char                     *output_buffer
);

---

🌸 DESCRIPTION 🌸

so the format you're working with here is the one that got set using qb_log_format_set(). and the whole point of this function is that it's intended to be used from your custom logger function 🫶 like, your logger, the one you wrote, calls this to get the pretty version out. iconic behavior honestly.

---

💖 STRUCTURES 💖

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

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;
};

like... every single log message gets one of these. it's giving main character energy for real 💫
